Grand Slammers sees sporting heroes enter HMP The Mount prison – home to one of the only remaining rugby pitches inside an adult male English prison – to attempt to build and train a team of inmates strong enough to compete against a formidable rival, the Australians.

Captain Martin Johnson, Jonny Wilkinson, Lawrence Dallaglio, Phil Vickery, Jason Robinson, Will Greenwood, Ben Cohen, Mike Tindall and Matt Dawson – each an England Rugby World Cup-winning legend who together as part of their best ever team, tasted glory in their country’s finest moment on a rugby pitch, lifting the William Webb Ellis trophy.
