Over Father’s Day weekend, architect Evan Webber is at home finishing a construction project and undergoing physical therapy for his injured shoulder while his wife and children are away on a planned vacation. His wife, Karen, a successful artist, entrusts her sculpture to her assistant Louis, who needs to deliver it to an art gallery for display.
Two young girls, Genesis and Bel, knock on Evan’s door in the pouring rain. Soaking wet, they tell him they are looking for the address of a party, but their phones are not working. Evan lets them in to dry off and use the Internet. The girls play with the family dog Monkey and flirt with Evan while he calls an Uber for them. They disappear into the bathroom when the driver arrives. Evan brings them clothes and finds them naked. He tries to convince them to leave, but they seduce him and he has a threesome with them.
The next morning, Evan finds his wife’s statue vandalized by the girls. He threatens to call the police, but they say they are underage. Vivian, his physical therapist, arrives, but when she encounters Genesis, who is pretending to be Evan’s lover, she angrily leaves. When Evan calls the police and begins reporting a break-in, the girls agree to be taken home.
The next night, after cleaning the house, Evan is attacked by Genesis and knocked unconscious. He wakes up to find himself tied to the bed, with Bel climbing on top of him and raping him, while Genesis records the scene on Evan’s phone. Evan breaks free and attacks Genesis, but she stabs him with a fork. She and Bel tie Evan to a chair with electrical cords, torturing him by forcing him to answer provocative questions about his affair.
Louis arrives at the statue and discovers the girls’ antics. He tries to free Evan, but has an asthma attack and realizes the girls have taken his inhaler. He trips, hits his head on the statue, and dies. The girls turn Louis’s body into a red statue and use both Evan and Louis’ phones to send text messages to make it appear that Louis discovered Evan’s affair with Louis’ wife, arguing with him, leading to Louis’ death. They claim to kill Evan at dawn as punishment for his adultery. They also reveal that they have been spying on Evan’s family for much of the weekend, planning their plot in detail.
The girls dig a grave for Evan in the yard and destroy the house. Upon finding Evan’s defensive gun, Genesis takes it and offers Evan a chance to escape if he can hide in the house. Injured and exhausted, Evan succumbs to the girls and realizes that no one in the neighborhood is home to call for help.
At dawn, the girls tie Evan up with a water hose, bury him in the hole, leaving only his head above ground, and say they will smash his skull with a large rock. The rock misses the boy’s head when the girls reveal that the entire game was just a “game”. They had no intention of killing Evan, nor the minor; everything they did was part of their hobby of seducing, raping, and destroying families of cheating married men. Genesis posts the video she recorded of Bel raping Evan to his Facebook page, making it public. They leave to find another victim and take Monkey with them, leaving Evan to his fate. Karen and the kids arrive to find the house destroyed.
