This film traces the path Pink Floyd took after the recording of the Animals album - an era when cracks in the band first started to show - and brings the strange story of the group and the intense relationship between Roger Waters and David Gilmour right up to date with the unexpected collaboration of these two maverick musicians at a 2010 charity event. Featuring numerous interviews with Waters, Gilmour, Richard Wright & Nick Mason, liberally interspersed with classic and rare performance footage, plus contributions from friends, colleagues and the finest rock journalists.
