Wallace & Gromit's Cracking Contraptions

Shopper 13 (1x10)

:

It's just a short nip to the shops but it can become a daily chore when you have all that cheese to carry home. Wallace has decided to save his legs by initiating a program of guided shopping trolleys to the supermarket. Mission 13 is the big one; he's going for the largest ball of Edam on the shelf. All seems to be going well until disaster strikes on the return leg. Can the heroic Gromit save the day by piloting the stricken craft back to 62 West Wallaby street or will the cheese be lost forever?
