Thirteen-year-old Becky Hooper is questioned about a recent incident at her family's lakehouse two weeks earlier. She gives vague answers and claims to remember only minor details. The story unfolds through her flashbacks.
Becky's mother died from cancer a year earlier, and she has a strained relationship with her father, Jeff. In an attempt to reconnect with her, they go on a trip to the family's old lakefront home. Meanwhile, prisoners Dominick Lewis, a Neo-Nazi, and his men Wallace "Apex" Landham, Sonny Cole, and Roman Hammond are transferred in a prison van. The group kills an inmate to get the van to pull over, kills the guards and escapes. They stop a car and steal it, killing the occupants in the process, a father and his two young children.
Jeff's girlfriend, Kayla, and her young son, Ty, arrive at the house, upsetting Becky. Jeff announces his engagement to Kayla. Becky storms out of the house, upset, followed by her Cane Corso dog, Diego. At her small fort in the woods, she knocks over a box of possessions, including a key whose bow is formed in the shape of a valknut. Dominick and his men show up at the family house, take everyone hostage, and demand the key. Kayla and Ty try to escape but are intercepted by Apex, who has grown tired of killing, and urges them to escape. Cole kills Dora, the family's other dog. Jeff lies about Becky's presence to protect her, but Dominick shoots Kayla to get the truth out of them.
Becky becomes aware of the assailants' presence and talks over a walkie-talkie, pretending to call the police in an attempt to scare them away. Dominick calls her bluff and tortures Jeff to lure her out. Dominick allows Jeff to talk to Becky, but Jeff tells her to run. Jeff breaks free and finds Becky, telling her he loves her, before Dominick shoots him dead. Dominick demands the key, but Becky gouges out his left eye with it then flees with Diego.
Dominick goes back into the house and sends Cole and Hammond to retrieve the key. Cole chases Becky back to her fort and tries to negotiate, but she ambushes and kills him with colored pencils and a sharpened ruler.
Apex shows Kayla and Ty compassion, and Dominick tries to have Apex reaffirm his loyalty to him. After finding Cole's corpse, Hammond chases Becky down to the lake, where she lures him into a trap, impaling his stomach. Hammond then falls into the lake, and Becky kills him with the propeller of an outboard motor. Apex finds Becky and her and incapacitates the dog but does not want to hurt Becky, and urges her to flee.
Becky makes her presence known to Kayla and Ty; Kayla tries to distract Dominick by asking him about the key's purpose. Becky sets off the car alarm to lure Dominick out, while Kayla frees herself. Apex fends off Dominick long enough for Becky to run a lawnmover over Dominick's head, and then shoots the apologetic Apex dead. Kayla and Ty join Diego and Becky to wait for the police.
In the present, Becky claims she does not remember the gang's deaths and lies about why they said they had come, with a cold look on her face, one hand nonchalantly playing with the key dangling on a string around her neck.
