Drama starring Katherine Waterston as Shirley, a typical teenager who spots an unusual business opportunity. Shirley is an average teen, preoccupied with her school grades and a crush on her best friend's stepbrother. When her babysitting job ends in a sexual encounter with the children's father (John Leguizamo) as he drives her home, he slips her a few extra dollars on top of her usual babysitting fee. Shirley quickly realises that there is a market for providing underage thrills to middle-aged married men, and employs several of her friends to provide similar 'services'. She is soon raking in the cash - but as the girls discover, such easy money comes at a price.
