Alicia takes refuge in an abandoned house to escape a raging storm. She kills an Infected in the kitchen and drags the Infected corpse through the living room.
More Infected emerge, and Alicia kills them each in turn.

Charlie bolts out of a closet and locks herself in a room. Alicia reels from the shock of seeing Charlie and warns Charlie that she should not be in the house.
After filling a bag with food, Alicia grabs a set of car keys and leaves the house. The car door flies open in the wind and knocks her unconscious.
She awakens inside the house. Alicia storms upstairs and tells Charlie that she will probably end up killing her given everything Charlie has done. Alicia calls Charlie “garbage” and hopes she lives to an old age so that she can live with the guilt of killing Nick. Charlie removes a gun from her bag and cries.
In the living room, Alicia destroys a piece of furniture to use it as firewood. She notices a shutter banging against a window.
Alicia goes outside and tries to hammer the shutter closed, but it blows open. She notices that Charlie covered the dead family with sheets.
Upstairs, Charlie dries off the family photos that Alicia had dumped outside. Alicia asks Charlie why she covered the bodies. Charlie remains silent. Alicia orders her to come downstairs.
Alicia enlists Charlie’s help in hammering the shutters closed. The hammering sound attracts Infected to the house. Alicia and Charlie run inside and nail the front door shut.
Alicia orders Charlie to hand over her wet jacket so that she can dry it by the fire. Charlie reluctantly obliges. Alicia finds a gun in the pocket and aims it at Charlie’s head, asking if Charlie intended to kill her. Charlie shakes her head but remains silent, then runs upstairs.
Alicia unblocks the chimney and cries when a dead bird falls out.
Upstairs, Charlie gazes at the family photos then looks at the Infected impaled on the tree. She opens the window.
Alicia tries to start a fire in the fireplace. A gust blows through the house, alerting Alicia to the open window.
Charlie steps onto a balcony and walks right up to the impaled Infected. The Infected grabs Charlie. Alicia pulls Charlie away just in time.
Alicia sits down with Charlie and realizes that Charlie intended to use the gun on herself. Charlie finally speaks up and asks Alicia why she saved her. Alicia insists that she’s not forgiving Charlie.
Alicia cooks canned food over the fire. While eating dinner, Charlie asks Alicia to describe the beach because she was supposed to visit the beach in Galveston with her parents at the time of the fall. Alicia tells Charlie to get some sleep.
Alicia wakes up and finds Charlie missing.
Charlie sorts through the family photos upstairs. Alicia finds her and declares that everyone who cared about the family in the pictures is now dead. Charlie insists that someone might come back for the photos.
Alicia tries to start another fire in the fireplace. The winds intensify. An Infected breaks through a window then gets tossed around by the gusts. Alicia and Charlie flee to the basement, which they find flooded. Debris collapses on the basement door, trapping them in the basement.
Alicia tries to open the basement doors, but they're locked from the outside. Alicia and Charlie stand on boxes to keep their heads above the rising water. Charlie explains that she saw her parents turn and can no longer remember what they looked like before they were infected. Confident that they will die in the basement, she begs Alicia to shoot her so that she doesn’t turn. Alicia holds the gun to Charlie’s head but lowers it when she remembers Nick and Madison. Something falls onto the doors, breaking the lock. Alicia and Charlie escape.
Outside, the impaled Infected walks toward Alicia and Charlie. Alicia kills it. They realize that the Infected fell onto the doors and saved them.
After the storm is over, Alicia places stones on the family’s graves. She leaves family photos by the graves in case someone returns for them.
