Sixteen-year-old Bart Lively desperately wants to feel comfortable in his own skin. The macho culture of his swim club is wearing him down and being a jock doesn't mean he isn't the target of gay jokes. Drawn to the art and athleticism of sychronised swimming, he jumps at the chance to become the first boy on the team, even if it means others start questioning his masculinity even more. All the while he starts falling for his teammate Erika, and falling in lust with her synchro rival Chelsea ... not to mention a cute boy in the diving club, leading him to question what it means to be a boy.
