It's the night before Gromit's birthday and Wallace is in the shed planning a surprise: a party for Gromit with lots of balloons and lashings of home brewed cheese. It's a surprise all right when Wallace goes overboard with the helium and the shed disappears into orbit - where zero gravity makes the Home Brew Cheese Kit go into hyperdrive.

Soon Mr Patel's greenhouse suffers a close encounter of the direct-hit kind and, with West Wallaby Street facing its very own Edamgeddon, Wallace assembles a crack team to journey into the unknown.

Thus man and dog journey blast off into space and, with First Knitting Officer Wendolene and Bill 'Cheesy' Cheeseman also aboard, Crackers in Space may be Wallace & Gromit's cheesiest mission yet.
