Maddie is working as an Uber driver in Montauk, New York. She’s already struggling to make ends meet but when her car gets repossessed she looks set to face bankruptcy if she can’t find a solution. Desperate for something, she accepts an unusual posting on Craigslist that would win her a Buick Regal. In exchange for the car, she needs to date Percy, the introverted son of the helicopter parents behind the ad. Hoping to bring him out of his social seclusion, the parents agree that Maddie will seduce him and become Percy’s girlfriend in order to teach him about adult life. But unleashing the full force of Percy’s pent-up adolescence has consequences no one could imagine.
