A half-dead Texas border town is rudely awakened when a series of grisly murders occurs, and the town is convinced a chupacabra is responsible. Four high school students craft a plan to capture the werewolf, but one man's racism complicates an already horrific situation and adds to the town's hysteria. What begins as a supernatural panic leads to a town divided and a group of young people battling two very different forms of beastly terror.
