After getting ousted from his job in the NCAA for throwing a chair at a referee, a hothead men’s basketball coach Marvyn Korn must take a job at Westbrook School for Girls, a private all-girls high school, in an effort to redeem what's left of his career and reputation.

Marvyn’s latest plan toward relevance is to get his team broadcast on ESPN and his method is to recruit an unlikely player: Ava, a gutsy beach volleyball phenom whose public tantrum got her ousted from her own sport. Between losing their assistant coach Holly Barrett to a rival school, new friction amongst teammates, a sudden and unexpected proximity to boys, and off-the-court disasters that no one could’ve predicted, this season, the Westbrook Sirens have even more to prove.
