Based on the fictionalised story of a prison inmate (John Simm) doing time for drug smuggling and his relationship with his wife (Shirley Henderson) and four children. The film will combine documentary and fiction and will be shot over a 5-year period, to enable Winterbottom to explore the changing dynamics of a prisoner's relationships. - from britfilms.com

 This is the third project directed by Michael Winterbottom with John Simm in the cast, the previous ones being Wonderland and 24 Hour Party People. Coincidentally, Shirley Henderson is also in those two films, but had little to no interaction with him in them.
