Nemesis Party

It's Glendale High's last house party of the summer, where you’ll either win over your long-time crush, Emma Winters, or lose her forever. The problem: your ex-girlfriend, Tara, will be there, and she’s out for revenge. You broke up with her, and now she’s trying to get every girl at the party, including Emma, to hook up with the school’s star basketball player - an old nemesis who is as cunning as he is tall, muscular, and hung.
