It's "The Impossible Planet", In the Style Of 24... In Space The Doctor and Martha land the TARDIS aboard a spaceship, only to have the room they landed in rise to unbearable temperatures, trapping them aboard the ship, which is being pulled into a nearby sun. Martha and the Doctor have only forty-two minutes to save the ship, the crew, and themselves. Meanwhile, a member of the crew has contracted a mysterious illness. His body temperature rises to an impossible height just before he opens his burning-white eyes and absolutely fries a fellow crewmember to a scorch on the wall.
