Becky

Thirteen-year-old Becky Hooper is grieving her mother's recent death from cancer and barely speaking to her father Jeff. He hauls her out to the family lake house for a weekend without telling her in advance that his new girlfriend Kayla and her young son Ty will be there too. Becky storms off into the woods with her dog Diego.

Across the state, four convicts — led by the neo-Nazi Dominick — escape a prison transport. Dominick had once lived at the lake house and hid a small key carved with a swastika under a floorboard there. The key matters to him very much. At dusk the four converge on the property and take Jeff, Kayla, and Ty hostage inside.

Becky returns from the woods, sees what is happening through a window, and slips down to her childhood treehouse hideout, where she has a backpack of supplies and a long-standing inventory of grievance. She finds the key in her room and refuses to surrender it. To flush her out, Dominick tortures Jeff in front of the house and ultimately cuts his throat when she still will not give it up.

Apex, the largest of the convicts — a Black inmate who joined the breakout for survival but draws a clear line at Dominick's racial politics — turns on the leader and is killed for it. Becky begins to pick the others off one by one in the woods, using her terrain and supplies: drowning one, blinding another with a ruler driven through an eye, putting a third through a boat propeller. The forest becomes her killing ground.

Dominick finally tracks her down in a face-to-face confrontation. Becky drives both thumbs into his eyes and beats him to death. She walks out of the trees with Diego at her side, blood-soaked and silent. Kayla and Ty are still alive in the house. The film closes on Becky's face — emptied out, holding a knife she will not put down.
