The show stars two rats, Rapido and Razmo, aboard the S.S. Wanderer, a cheese ship with no actual destination. The focus of the series is on the adventures of the two rats, including guarding the cheese, interacting with other stowaways and various ill-fated encounters with the crew. The rats themselves live in the hull of the ship in a lavish two-bedroom apartment.
