A group of minor bank robbers gets more than they bargained for when they come into conflict with an army of sentient rats. Hilarity ensues when the rats, too, realize they are in over their heads, as a feline conspiracy reveals itself.
A group of rats led by a giant rat who "makes all the rules" infiltrate a castle which appears to belong to 4 criminals, whom are led by "Dick Dastardly Richard". The Criminals are planning on stealing the Mayan treasure (which is a treasure chest with gold inside). The 4 criminals make their way to a dinner which is in the city. In the back of the dinner is a Mayan temple which is home to the Mayan treasure. The criminals find the treasure chest but are confronted by "Garrod, guardian of the treasure chest of the Mayan Temple". But Garrod is defeated by the rats from the beginning of the film who appear to have followed the Criminals to the Temple. The Rats then steal the Treasure killing two of the criminals. The rats manage to outsmart the police who are outside of the dinner by convincing them they there are no rats in the dinner. But then Cat police (who are distinct from the regular police) show up and discover a rat on the shoulder of a one of the officers. The Rats then steal a police car but crash into a Cat police road block. Then the earth explodes.
