A culinary adventure for the whole family Remy is a rat. A very special rat, however, because Remy has a very keen sense of taste and smell. Unlike his relatives, he has no love for rubbish and spoilt food, he appreciates tasty ingredients and fine spices. Remy loves the art of cookery more than anything else and idolises the French master chef Auguste Gusteau. One day, Remy has to leave his family and his home head over heels. Under dramatic circumstances, he flees to Paris. During this escape, the ghost of the now deceased master chef Gusteau appears to him and leads him to the roof of his former restaurant. This has far-reaching consequences.
