Melanie Donner has certain...urges. Bad urges. Urges she knows she needs to get control of, or she's going to end up either in prison or dead. When her two best friends decide to make a pact to each pick up a guy to spend the night with on every major holiday, she figures it's a good way to set a few boundaries for her little "hobby". But right from the start, things get weird when a would-be student of her work shows up and won't take no for an answer...
