Rebellious, quick-witted Erica Vandross (Zoey Deutch) is a 17-year-old firecracker living with her single mom Laurie (Kathryn Hahn) and mom's new boyfriend Bob (Tim Heidecker) in L.A.'s San Fernando Valley. When Bob's mentally unbalanced son Luke (Joey Morgan) arrives from rehab to live with the family, Erica finds her domestic and personal life overwhelmed. With Luke and her sidekicks Kala (Dylan Gelula) and Claudine (Maya Eshet) in tow, Erica acts out by exposing a dark secret of high-school teacher Will (Adam Scott), with perilous results; their teenage kicks become a catalyst for growing up in unexpected and unpredictable ways. Mixing dark comedy and teenage angst writer-director Max Winkler (CEREMONY) and co-writer Matt Spicer (INGRID GOES WEST) re-imagine an unproduced script by Alex McAulay, creating a star vehicle for blossoming talent Zoey Deutch (BEFORE I FALL, WHY HIM?) and elevating the teen movie to new heights.
