The animals at the Franklin Park Zoo love their kindhearted caretaker, Griffin Keyes (Kevin James). Finding himself more comfortable with a lion than a lady, Griffin decides the only way to get a girl in his life is to leave the zoo and find a more glamorous job. The animals, in a panic, decide to break their time-honored code of silence and reveal their biggest secret: they can talk! To keep Griffin from leaving, they decide to teach him the rules of courtship - animal style.
