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.
