... Killer. Thus destroying the twist. However the film is still worth watching for possibly Andy Garcia's last film appearance where he was moderately hot. Ashley Judd always delivers. And this cast is excellent. You hear a certain sound throughout this film and it's what you hear right before the nastiness occurs. Watch out for a brief, one scene (uncredited), cameo by Veronica Cartwright who also appears, credited, in the director of this films other San Francisco set thriller Invasion of the Bodysnatchers (1978). Also future Tomorrow People baddie appears and he's as hot then as he is now.
