Grand Slammers | Preview (ITV1)

England's Rugby World Cup-winning legends have come together after 20 years to take on a unique challenge behind the walls of a jail - using the power of sport to turn around prisoners' lives.

In this brand new two-part documentary, members of the 2003 side including captain Martin Johnson, Jonny Wilkinson, Lawrence Dallaglio, Phil Vickery, Jason Robinson, Will Greenwood, Ben Cohen, Mike Tindall and Matt Dawson attempt to build and train a team of prisoners to be strong enough to compete against a formidable rival, the Australians.

Playing out over two consecutive nights during ITV's exclusive coverage of this year's tournament, Grand Slammers sees the heroes enter HMP The Mount – home to one of the only remaining rugby pitches inside an adult male English prison.

The legends are aiming to show their novices the spirit of rugby and its broad appeal with all the camaraderie, intensity, emotion, buzz and laughter that comes with being part of a team focused on a common goal.

Two decades ago the England players inspired a nation - now, with only two months to get their team ready, can they use the power of rugby to inspire the prisoners to glory?

In the first episode, rugby legends Martin Johnson, Lawrence Dallaglio and Mike Tindall reunite behind the locked gates of HMP The Mount, facing an intimidating challenge - recruiting a group of prisoners who have very little idea of what the sport involves.

The second episode culminates in a once-in-a-lifetime rugby match where the legends play alongside the prisoners they’ve trained to recreate the historic Rugby World Cup final from 20 years ago - this time against a team of ex-pat Australian rugby players bossed by legend George Gregan.

Grand Slammers airs Wednesday 27th and Thursday 28th September on ITV1.
