Mr. Twardowsky has spent years alone aboard a space station on the Moon. That's the price of a deal he once made with the Devil. Bored beyond endurance and unwilling to accept his fate, he seizes a final chance when the Devil appears in the form of a beautiful woman. Desperate for one last return to Earth, he pleads for more time. When he realizes no bargain is possible, he flees, knowing he can only postpone the inevitable. Eventually, every deal with the Devil must be paid in full.
