Seventeen-year-old Erica Vandross (Zoey Deutch) propositions pedophilic men in her town before blackmailing them in order to save money for her father's bail. When her mother Laurie (Kathryn Hahn)'s boyfriend Bob Sherman (Tim Heidecker) brings his son Luke (Joey Morgan) home from rehab to live with them, Erica realizes that Luke is hiding something about a high school teacher in town (Adam Scott)...and it's a problem she can help him with.
This film contains examples of:
- Accidental Murder: Luke accidentally kills Will by pushing the latter onto a coffee table... and impaling him on an Eiffel tower figurine. Since he was roofied, this is not apparent right away.
- Blended Family Drama: Erica apparently scares off all her mom's boyfriends and resents that Bob and now Luke are invading her space.
- False Rape Accusation: Variation. Will's sexual harassment case was thrown out and he considers it a desperate cry for help by the accuser. Luke later admits that he was lying, but he did see Luke molest a female classmate and lied that he was abused to protect her.
- Fille Fatale: Erica is explicitly seventeen. Her m.o. is to charm older men and give them a blowjob while her friends obtain evidence of this act. The three of them then blackmail the guy for engaging in sexual acts with a minor and extort money out of him.
- Flirty Stepsiblings: When told to comfort Luke, Erica offers him a blowjob. Luke is aghast at the possibility of getting a blowjob from his future stepsister. However, he confesses his love for her later and they have sex.
- The Ghost: Despite Erica's father being her primary motivation, he never makes an appearance beyond a photograph in Erica's locket.
- Meet Cute: Invoked by Erica, who stages a cutesy bump-in 'first meeting' at the grocery store in order to charm Will.
- Run for the Border: After Luke and Erica find Will's dead body, they make a break for Mexico. Erica decides she doesn't want to live her life on the run and says she'd rather turn themselves in.
