Roddy is a decidedly upper-crust "society mouse" who lives the life of a beloved pet in a posh Kensington flat. When a sewer rat named Sid comes spewing out of the sink and decides he's hit the jackpot, Roddy schemes to rid himself of the pest by luring him into the "whirlpool". Sid may be an ignorant slob, but he's no fool, so it is Roddy who winds up being flushed away into the bustling sewer world of Ratropolis. There Roddy meets Rita, an enterprising scavenger who works the sewers in her faithful boat, the Jammy Dodger. Roddy immediately wants out, or rather, up; Rita wants to be paid for her trouble; and, speaking of trouble, the villainous Toad—who royally despises all rodents equally, making no distinction between mice and rats—wants them iced... literally. The Toad dispatches his two hapless hench-rats, Spike and Whitey, to get the job done. When they fail, the Toad has no choice but to send to France for his cousin—that dreaded mercenary, Le Frog.

According to Peter Lord, co-founder of Aardman, this film's original concept involved pirates, and was pitched to Dreamworks soon after the release of Chicken Run. However, Aardman were told that there was no market for pirate films (this was before Pirates Of The Caribbean was made), and were told to modernize the concept. By the time the writer had done this, the project was temporarily shelved to make way for the production of Wallace & Gromit In The Curse Of The Were-Rabbit.

The film uses software that was developed for the rabbits floating around the Bun-Vac 6000 in Wallace & Gromit In The Curse Of The Were-Rabbit. The software reproduces the 'imperfections' found in clay-mation (i.e. dropped frames, thumb-prints, etc.).

Andy Serkis beat Robert De Niro and William Shatner to play the part of Spike.

Jean Reno beat Stellan Skarsgård, Kevin Kline and Johnny Depp to play the part of Le Frog.

In the first theatrical trailer, Roddy was not the only pet of the little human girl. There was also a cage with two small yellow gerbils, who seemed to be Roddy's menservants. However, in the final cut of the film, these two characters were removed, probably to advance the story and make Roddy appear to be a character who is more "alone" than "spoiled".

Aardman's first fully-CGI feature film. The reason for using computer animation instead of the studio's trademark clay animation was the large amount of scenes involving water, which is nearly impossible to do convincingly in stop motion.

Hugh Jackman also provided the screams for the slug that Roddy first meets in the sewer.
