Ruby Weaver has man trouble: she tries to fix them, so she's stuck herself with a string of losers. Her current lover, Sam Deed, seems different: he's sweet, tender, just in from Dubuque. But as Ruby tells her therapist about Sam, in flashbacks we see someone not of this world. In fact, Sam informs Ruby that he's from the future, 2470 to be exact, travelling back in time to avoid prosecution.
