Lister’s attempt to activate a second hologram – his dream date Kristine Kochanski – goes horribly wrong and creates Rimmer’s ideal companion instead: himself. Moving into their own shared quarters, the two Rimmers quickly drive both the crew and each other mad, the city-sized Red Dwarf proving too small for such an insufferable pair. Before long, the conflict has escalated to the point where only one Rimmer can survive – and it falls to Lister to decide which.
