A teenage girl, Alfa, is found drifting in space by Maria Nova, a lonely, slightly perverted middle age lesbian yandere with no social skills. Maria is running a space station half way between earth and a distant planet, handling girls that are being sent out for an unspecified reason. She has to revive them and hold them for four years. She immediately she sees that she does not need to ship Alfa out, thus believes her the perfect life partner. Alfa befriends some of the girls, and they have various adventures with Maria Nova's clumsy and terrifying amourous advances, her weird assistant, and spacebugs. It is sort of like "Maria sama ga miteru" meets "Alien Resurrection."
