Remy is a rat with a highly-gifted sense of taste and smell. He wants to become a chef like his idol, the recently deceased chef of a five-star french restaurant. Remy's large family objects because a rat would be feared upon as a common pest in the human world. He soon winds up separated from his clan and finds the restaurant, where he teams up with the clumsy garbage boy, Afredo Linguini who wants to become the restaurant's new chef. He discovers that pulling Linguini's hair makes him move, and this may be Remy's key to finally cooking for the first time. All Linguini has to do is hide the fact that a rat is helping him cook.
