Several people are in a "happy house. One man is there because he insists he is from another planet, and is waiting for rescue. He describes another world and society, and it sounds very nice. //skip main movie//
One day he says he has been contacted and he will be rescued at a specific time. He invites one or two of the residents. One sort of agrees, and one does not.
The rescue is to be in the middle of the night. Next morning, he is gone without a trace and so is one friend.
A nice movie that I would watch again if I could just remember the name.
