River Milton and Maxine Hoffman have been sworn enemies since kindergarten. When it comes to romance they are complete opposites, with River constantly being dumped by her "more adventurous" girlfriends and Maxine being stuck with her troubled long-term girlfriend. One day after another public humiliation from Maxine, River steps up to her enemy with a piece of cupcake in hand as a peace offering. Maxine readily accepts the truce and when she wakes up the next day, things take a drastic turn, though in River's favour. But when The Peace Offering proves to have a fatal effect on Maxine, a guilt-stricken River is forced to face the consequences on her own.
