In response to the attack on Meereen, Daenerys decides she will crucify the Masters and destroy their cities. Tyrion likens Dany’s plan to her father, who planned to King's Landing with wildfire, and suggests “an alternate approach.”
Daenerys and her council meet with the three slaver envoys, who assume they are negotiating Daenerys' surrender. The trio inform the queen the Unsullied and Missandei will be sold to the highest bidders, and the dragons slaughtered. Daenerys clarifies her position by climbing onto Drogon and leading her three dragons to lay waste to the slavers’ warships, while Daario and her Dothraki horde cut down the Sons of the Harpy surrounding the city.
Missandei tells the envoys one of them will die as punishment for breaking their pact. Razdal and Belicho shove Yezzan forward, but Grey Worm slashes Belicho and Razdal’s necks instead. Tyrion charges the still-startled Yezzan with telling his people what happened “when Daenerys Stormborn and her dragons came to Meereen.”
In a field outside of Winterfell, Jon Snow and his supporters meet with Ramsay Bolton and his contingent. Ramsay tells Jon to kneel and all will be pardoned. Agreeing there is no need for thousands to die, Jon offers to fight one-on-one instead. Ramsay declines and reminds them he has Rickon, presenting Shaggydog’s head as proof. Sansa coolly tells her husband he will die the next day. Looking at the men, Ramsay comments his dogs have not been fed in a week. “In the morning then, bastard,” he says.
Jon, Davos, and Tormund lay out their battle plan while Sansa listens from the side, excluded. Clearly outnumbered, they determine it is crucial that Ramsay’s men charge first. Once alone with Jon, Sansa voices frustration she wasn't consulted given her knowledge of Ramsay. When Jon asks how she suggests they get Rickon back, she says they probably never will. “As long as he lives, Ramsay’s claim to Winterfell will be contested,” she explains. Admitting she knows nothing about battles, she advises Jon to not do what Ramsay wants. Jon scoffs at the obviousness of her suggestion, but Sansa insists that what's most obvious is they should have waited to build a stronger force. “Battles have been won against greater odds,” Jon says. Sansa makes one thing clear: should Ramsay win, she will not go back to him alive.
Disturbed by his conversation with Sansa, Jon tells Melisandre she is not to bring him back should he fall in the battle. The priestess denies his request, reminding him that she serves the Lord of Light, not him. She does admit, however, that the Lord of Light might only have brought Jon back to die in the battle anyway.
Discussing Stannis Baratheon and Mance Rayder, Davos posits to Tormund their mistake might have been believing in kings. “Jon Snow’s not a king,” Tormund replies, and leaves for a drink.
Walking the camp all night, Davos discovers snow-covered mounds of charred timber, the remnants from Shireen’s pyre. Amongst the ruins he finds the carved stag he made for Shirren, completely scorched. Before he can process what this means, a war horns sounds in the distance. It’s time for battle.
Daenerys and Tyrion receive the Greyjoy siblings, who offer their ships in exchange for Dany’s support of Yara’s claim to the Salt Throne. Acknowledging Euron will have his own pitch, they explain that Euron’s overture will include a marriage proposal. Daenerys is intrigued by Yara, but states that, unlike their fathers, they will leave the world a better place – the days of reaving and raping are over. Hesitating momentarily, Yara agrees to give up the Ironborn way of life. The two clasp arms in agreement.
Jon’s troops stand in formation across the battlefield from the much larger Bolton army. Ramsay leads Rickon by rope to the front of the lines and surprises everyone by cutting Rickon’s binds. Releasing the boy, Ramsay tells him to run to his brother. Rickon sees Ramsay’s bow being brought to him and speeds toward the other side. Disregarding caution, Jon leaps onto his horse and races to reach his brother before the arrows do, but fails. Rickon is struck down and Jon, overcome with rage, loses sight of his side’s careful strategy and charges the Bolton army. The Stark troops follow their leader into battle while Ramsay commands his archers to loose and his cavalry to charge. Staggering to his feet after his horse is hit, Jon prepares to face oncoming death, but is saved by the arrival of his cavalry, which collides with the Boltons’
Men and horses fall everywhere, especially where the two cavalries met. As bodies start to pile up, Davos and his archers drop their bows, draw swords, and rush forward. The Bolton forces then march forward and surround the Stark supporters with a shield wall, and lower their spears. Wun-Wun the Giant and Tormund attempt to break through, but the shielded troops move forward, skewering Jon’s men and crushing them against each other. When the wildlings try to flee over the pile of bodies to their rear, they’re met by Ramsay’s own infantry, led by Smalljon Umber.
Tormund and Smalljon exchange blows, and it looks like Tormund has finally met his match. Jon is knocked down and might be trampled to death. Ramsay watches his imminent victory with glee from the safety of the high ground. Jon finally claws his way above the fray, looks around, and knows the battle is lost. Then a warhorn sounds -- the Knights of the Vale have arrived. From a distance, Littlefinger and Sansa observe as the Vale cavalry break the Bolton lines. Tormund gouges out Smalljon’s eyes and finishes the kill. Jon spots Ramsay headed back to Winterfell, and he, Tormund, and Wun-Wun tear after the Warden of the North.
Ramsay bars the gate, confident he can wait out any siege. Wun-Wun, using what’s left of his energy, breaks through the heavy doors. The giant’s body shields the wildlings from the Bolton arrows, allowing them to rush into the courtyard and take it. As Jon goes to see to Wun-Wun’s wounds, the last of the giants is killed by an arrow to the eye. Ramsay, standing with bow and quiver, taunts Jon, “You suggested one-on-one combat, didn’t you?…I’ve reconsidered.” As Ramsay draws and looses, Jon snatches a shield and blocks the arrows with singularly focus. Finally he reaches Ramsay and pummels him. He stops only when he sees Sansa: Ramsay is not his to kill. The Stark banner goes up and Jon instructs his men to bury Rickon in the crypt, next to Ned.
Sansa heads to the kennels where the bloodied Ramsay is chained to a chair. Her former torturer tells her, “You can’t kill me. I’m part of you now.” As the hounds pad forward, Ramsay is confident his beasts are loyal. “They were,” Sansa says, “but now they’re starving.” An animal sniffs, then rips into Ramsay’s face. He screams as the other dogs join in. Sansa watches for a moment then turns away, smiling at her revenge.
Daenerys meets with the slave masters to negotiate terms of surrender, but they refuse it. She then rides Drogon, as Rhaegal and Viserion assist them in burning the slaver's fleet. Grey Worm kills two of the masters, leaving one to tell of what he had witnessed. After the battle, Theon and Yara meet with Daenerys and Tyrion and agree to an alliance. The Starks and Boltons meet before the battle, with Ramsay ordering them to surrender. On the following morning, the confrontation begins. Ramsay brings out Rickon and tells him to run towards the Stark army, firing arrows at him as he does. Jon tries to save him, but Rickon is killed by an arrow. The battle ensues with the wildlings becoming pinned by Bolton soldiers, but they are rescued by the Knights of the Vale. Ramsay flees inside Winterfell but Wun Wun manages to break the door down, being killed afterwards. Jon almost beats Ramsay to death but eventually stops, and takes him as prisoner. Sansa visits Ramsay at his cell and watches as his starving hounds devour him.

In the battle, the Stark forces are pinned by Bolton soldiers, but are rescued by the Knights of the Vale.

Mereen is assaulted by flaming catapults, Daenerys watches impassively. Tyrion attempts to explain what happened, the Queen says she is prepared to fight. Tyrion mentions that her father Aerys Targaryeon had planned to burn King's Landing with wildfire hidden under major capital buildings, which was why Jaime had killed him. In a cease fire three Slave Masters arrive and state their terms for surrender. Daenerys turns the tables and demands their surrender. Drogon appears, Daenerys climbs on and flies away. The other two dragons break out of their cell. The three flying beasts proceed to burn the attacking ships and soldiers. The battle over, Tyrion then proceeds to reprimand the three Slavers and Grey Worm kills two of them. Ramsay Bolton and his retinue arrives for a parley with Sansa and Jon at centre field. He mocks them, reminds them he has Rickon, and refuses Jon's offer to settle things one - on - one. They break away with the formal battle set for the next morning. Jon and his War Council strategize, with a smaller force they will try to dig trenches, absorb a charge, and prevent any flanking attacks. Sansa seems pessimistic and warns Jon that Ramsay is setting a trap, she is upset her advice wasn't considered. Sansa is also fatalistic and says they can't save Rickon. The two argue, Jon expresses his confidence against the odds. Davos and Tormund chat, the Wilding offers a drink of fermented goat's milk but Davos wants to walk alone until he shits his guts out. Jon goes to talk to the Red Witch, she seems depressed and has no advice. Jon tells her not to "bring him back" if he dies, she says it is out of her control, the Lord of Light decides, and there is a reason Jon was recovered. Outside of camp, in the darkness, Davos comes across an old fire. Kicking the burnt wood he finds the small carved stag he had given young Shireen Baratheon long ago. He then realizes what happened there. Tyrion and Daenerys meet Theon and Yara Greyjoy. Unaware of all Theon has gone through he mildly insults the man, they are surprised when Theon says he is unfit to lead the Ironborne. In return for the Iron Islands the Greyjoys offer their ships and support Daeyneris' claim to the Throne. The women shake on it with the Westeros arm lock. Outside Winterfell the two armies face each other quietly a few hundred metres apart. The imposing and more numerous Bolton ranks stand firm. Ramsay rides a horse leading Rickon Stark by a rope. He holds a short sword high, then plunges down and cuts Rickon's bonds. He tells the frightened teen to run towards Jon. Rickon takes off across the no-man's land, Jon mounts his horse and races toward him. Ramsay playfully shoots arrows at Rickon getting closer each time. Near halfway an arrow kills Rickon before Jon can reach him. Enraged, Jon Snow continues on toward the Bolton army. Davos and Tormund are dismayed but rally and lead their troops forward. Ramsay commands his longbows to fire, Jon's horse is hit and he falls to the ground. The Bolton Cavalry charges at him. Taking up Longclaw he prepares to meet the charge, suddenly his own Cavalry are there and the armies clash. Ramsey's archers continue to fire into the melee which is brutal hand to hand combat. Davos then leads the Reserve forward and Smalljon Umber leads more Boltons into the fray. The bodies pile up. The Bolton troops completely surround the Snow forces and link their shields tightly with long pikes. Slowly the circle tightens as the Wildings try to break through in vain. The Giant Wun Wun even has trouble and is riddled with arrows. At one side a large mound of bodies give some hope to escape. Jon is trapped under the mob of men and struggles to get up. Tormund engages Umber. Now all are pushed in tight. A horn sounds in the distance, Ramsay looks to his right and sees a large cavalry force join the battle, Sansa and Littlefinger leading. The blue and white horsemen of the Vale smash through the Bolton army. Ramsay retreats to Winterfell followed by Jon and Wun Wun . Wun Wun smashes the main doors to break into the castle but pays the ultimate price. He gazes at Jon as he dies, Ramsay firing the last arrow into the Giant's eye. Ramsay now fires arrows at Snow, but Jon grabs a shield and protects himself. He gets to Bolton and beats him to a bloody pulp. The Stark wolf banners are draped from the walls. Jon tells Tormund to bury Rickon in the Crypt. Sansa goes to the dog kennel where Ramsay is alive and tied up in a cage. Knowing his end is near he still tries to insult her, she tells him all trace of him will disappear, then releases his hungry hounds. They attack and chew his face, Ramsay Bolton dies screaming.
