A radiation leak has killed everyone on board

except for Ranma Saotome, who was in stasis during the leak, and his
pet pig, who was safely protected in the ship's hold.
 Revived, three-million years later, Ranma's only companions are,
Ryouga, a creature evolved from Ranma's pet, and Tatewaki Kuno, a
hologram of one of the dead crew.

You REALLY should keep Lister, Cat, and Smeg Head (Rimmer). I'll go clean my
guns now.
