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. A group of zoo animals decide to break their code of silence in order to help their lovable zookeeper find love, without opting to leave his current job for something more illustrious.
