A comedy series about a group of banged-up petty crooks and the family, friends - and fiends! - who visit them each week in their natural environment: a low security prison. Set almost entirely in the prison visiting room, the comic tension flows from a three-way dynamic between the prisoners, their family and friends, and the under-valued prison officers. It's about relationships under pressure and these 'windows' - the breaks to the monotonies of life which each visiting time brings - provide the stories within the programme. Each episode exposes a different prisoner and his world.
