All 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 the girl of his dreams is to leave the zoo and find a more glamourous job to win her over. The animals, in a panic, decide to break their time-honoured 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! Also featuring the voices of Cher, Nick Nolte, Adam Sandler and Sylvester Stallone.
