A pampered pet "society mouse" Roddy St. James (Hugh Jackman) thinks he's got it made... until he's literally flushed away to a bustling underground world of ninja frogs, hench-rats and singing slugs. In an attempt to get out, he meets an enterprising scavenger Rita (Kate Winslet) and a villainous Toad (Ian McKellen). This outrageously inventive adventure is a flood of fun.
