A cat, two guinea pigs, and a colony of brave sewer rats band together in order to save Freddy, a golden hamster, from an evil scientist who's discovered that Freddy can read and write, and plans to hamster-nap him in order to dissect his brain.

Freddy the golden hamster and his animal cohorts, along with a computerized, robotic golden hamster, travel back in time to Assyria, where some of them are captured by crusaders and Freddy gets a taste of undomesticated living.
