Kindhearted Griffin Keyes is one of the best-loved caretakers at the Franklin Park Zoo, but since he is more comfortable with the animals than with females of his own species, his love life is lacking. When Griffin decides that the only way to get a girlfriend is to find a more-glamorous career, the animals panic. To keep him from leaving, they reveal their secret ability to talk and offer to teach him the rules of courtship, animal-style.
The story follows a down-on-their-luck couple who discovers a serial killer's film reels. They decide to take the law into their own hands, risking everything for the chance at a $100,000 reward. It isn't long until they find themselves in the killer's lethal cross-hairs.
