The date is the near future, where ten lucky guests are personally invited to help celebrate the opening weekend of the world's first Space Hotel, SPATEL. The guests themselves are as interesting as SPATEL itself. The world's leading brain transplant surgeon, who himself is enjoying his brand new body. A leading astronaut, and a wealthy couple who are there to plunder SPATEL's rich secrets. Then the bizarre, futuristic murders start, which somehow seem linked to the planets in the rooms which each guest has been allocated. With SPATEL refusing all contact with Earth for the weekend, the race is on to identify the true killer. Otherwise the shuttle will return on Monday to collect ten corpses. Or is everything a costly illusion, devised by the elusive and mysterious owner, Mr. Howarth?
