 As Kryten and Rimmer make a return trip from the cargo decks, the pair encounter a space-time phenomenon that prompts them to bring the others together to examine it.Struggling with the phenomenon's effect upon the ship, Kryten manages to reveal to the others that "Red Dwarf" has come within range of a white hole – a very rare spatial phenomenon that spews time into the universe, much as a black hole sucks matter from it.The group opt to ask Holly for help and activate her long enough to be given a solution – to use a thermonuclear device on a star to catapult a planet from its orbit and into the mouth of the white hole.
