Ben’s granny needs his help to pull off her biggest heist yet, stealing the crown jewels!
Meet Ben, an 11-year-old want-to-be plumber fed up with spending his Friday nights at Granny’s. All she wants to do is play Scrabble and eat cabbage – not exactly his idea of fun!
Hungry and bored Ben goes searching for something more edible in the kitchen and stumbles upon an old biscuit tin. The tin holds more than just digestives, however, it contains Granny’s biggest secret . . .
Based on David Walliams’ best-selling book.
