In a dead-end town in the Texas desert where nothing ever happens - something finally does, a series of gruesome murders.  While the townsfolk try to solve the mysteries, four local high school students uncover the truth - the killings are the work of Chupacabra, the legendary Mexican Werewolf that sucks the blood of goats, but now has developed a taste for humans.   Working against the bumbling and misdirected actions of the adults, the four students devise a plan to capture the beast and claim a lucrative bounty that will finally allow them to escape the confines of their backwards hometown.  But, when one of the girl's father utilizes the hysteria to enact his own agenda, the students are faced with a complication for which they are not prepared. They are left to stand against the racism and hatred pervading their town and take on the terror that has just crossed the border.
