In series three Kryten's amusingly shaped head becomes a permanent fixture on board Red Dwarf. The newly expanded crew runs amok through time and space, blithely ignoring the consequences of causality. Meanwhile, as Red Dwarf heads on a collision course towards a minefield of black holes, the crew is forced to abandon ship. Lister finds himself marooned on an arctic moon with Rimmer and only a tin of dog food between him and starvation. Sci-fi comedy starring Craig Charles, Chris Barrie and Danny John-Jules.
