Daniel and Beth, hearing noise upstairs, leave the basement party only to find the brothers holding them hostage within their home at gunpoint. Terrified, Beth offers the brothers the help of George, a doctor, who begins to tend to Johnny's injuries. Addley forces Beth and Daniel downstairs, trapping all the party-goers in the basement at gunpoint. Ike calls his sister Lydia (Deborah Ann Woll), who informs him that she and their mother lost the house and will be on their way to help the boys.A short time later, an RV arrives with Lydia and Mother (Rebecca De Mornay). Mother becomes very angry at Ike for losing the emergency phone they use to contact one another, telling him she was unable to alert him of losing the house. Realizing the gravity of the situation, Mother arranges help to sneak over the border into Canada, however it will cost ten thousand dollars. She learns of her sons sending money to the house which she never received, before going into the basement. Mother is initially nice to the hostages, explaining to them that no one has to get hurt. She confronts Beth and Daniel about the money, however both deny knowing about it. Mother believes Beth, however she has Addley and Ike torture Daniel for information. Just then Melissa attempts to escape, only to be shot by Addley. Mother takes the cellphones, bank cards and pin numbers of the others and makes Ike take Beth to a cash machine to collect the money.

Daniel assures the officer everything is fine and he leaves, alerting Mother of Daniel's lying skills. She further becomes suspicious after Lydia discovers a Valentine's card from Daniel to Julie, as well as photographs and newspaper articles of a child killed in a car accident. Ike and Beth dispose of Melissa's body behind a dumpster, where she is soon found to be alive by two sanitation workers who rush her to hospital. While at the ATM, Beth and Ike encounter two party girls, Vicky Rice (A. J. Cook) and Jenna Luther (Alexa Vega), who Ike quickly kills after they realize he has a gun. The pair travel to Treshawn's laundromat business to take money out of the safe, where Beth attempts to escape but fails. They later encounter the police officer who Ike also kills. Back at the house, George realizes Mother has been lying to Lydia about a rare skin condition and tries to convince her to help his friends, but Mother sends Lydia away. Johnny, now in critical condition, tells his mother he doesn't want to die a virgin. Mother forces Treshawn and Dave to fight over which one of their partners will be forced to have sex with Johnny.

Mother leaves the basement, before the group manage to arm themselves with knives. They lure Addley into the basement and stab him to death. Treshawn, now deaf and having difficulty seeing, takes Addley's gun and goes upstairs. Gina follows him, startling him and causing him to shoot her in the side. As Treshawn attempts to help his wife, Mother shoots him in the back, killing him. Mother discovers Addley's body and phones Ike, before forcing Beth to listen to her shoot Daniel. Annette and Julie are then taken upstairs and tied up.At the hospital, Melissa regains consciousness and alerts authorities to the house. George confronts Mother, telling her that none of her kids look like one another, and look nothing like her. Mother, enraged, threatens to kill him, but Lydia convinces her that they need George. Ike and Beth then burst through the front door with the money. Mother instructs Ike, Lydia and George to take Johnny to the RV while she has a chat with the ladies. Inside the RV, Johnny shoots George in spite of Lydia's pleas to let him live. Mother reveals to Julie and Annette that Beth was the one who hid the money and is the one responsible for all the deaths. Beth reveals that she was hiding the money for the baby she is expecting.
