Roddy St. James is an upper class pet rat who makes his home in a posh Kensington flat. While his owners are away on holiday, a common sewer rat named Sid comes spewing out of the sink and decides to stay, especially as England is playing against Germany in the World Cup Final. Roddy schemes to get rid of Sid by luring him into the toilet, but Sid is not fooled, instead throwing Roddy in and flushing him away into the sewer.
