Kelsey Darson falls from world to world doing what is needed of him in each new place. He meets a woman who tells him she is his lover, but he doesn't know this yet because they don't fall from world to world in the same order. He wonders why another man who falls from world to world keeps trying to kill him. He will find out in time that the strange man seeks revenge for a wrong not yet done by Kelsey, a wrong that Kelsey has done in revenge for an act the man does not yet know he is to carry out. Good, evil, love and vengeance play out in a complex, non-linear experience that reveals itself by the end to be elegant in its Moebius simplicity.
