Cass is a twenty-four-year-old preschool teacher who has spent the last year of her life consumed with heartbreak after Greg, her ex-boyfriend, left her for someone else.
One evening, Cass’s very patient and loyal best friend, Samantha, brings Cass to a lesbian party, in an effort to find romance and to get Cass out of the house. At the party, Cass, who is supposed to be Sam’s wing-girl, meets Amanda, a mysterious and intriguing party-goer who nobody actually invited.
Amanda attempts to seduce Cass, and although Cass is intrigued, it’s very clear that she’s still hung up on Greg. Amanda convinces Cass to confront Greg, but when she does, she discovers something nobody saw coming.
