Red Dwarf is a British sci-fi comedy show about the last human being, Dave Lister, that is stuck on a 5 mile long Jupiter Mining Corporation spaceship, Red Dwarf, as he tries to find his way back to Earth. Lister was locked into stasis because he tried to smuggle a cat on the ship. While he was locked in stasis, a radiation leak killed the entire crew and the Red Dwarf headed to the far reaches of space to keep the radiation contamination from spreading. Three million years later, Lister was released from stasis. With Lister on this mining spaceship is a being named Cat that evolved from his cat, a Series 4000 mechanoid named Kryten and a hologram of his bunkmate named Arnold Rimmer.
Kryten was a service droid on the spaceship Nova 5. Nova 5 crashed on an asteroid killing the entire crew. Kryten continued to prepare meals and dress the dead crew because he was programmed to serve. He even passed time by watching his favorite TV show (“Androids”). Three million years later, the remaining crew of the Red Dwarf (Dave Lister, Arnold Rimmer and The Cat) found and rescued Kryten. After his rescue, and a temporary leave of absence from Red Dwarf and a different actor to play him, Kryten has become an important part of the crew serving as a science officer, an important comedic role, and the occasional service droid duties (someone has to make Lister breakfast!).
Throughout the series of Red Dwarf, Kryten has rescued the crew, learned to lie, became human, went to prison, joined up with a band of renegade droids, fallen in love and had to continuously put up with Arnold Rimmer.
