Zac Hobson (Bruno Lawrence, As Time Goes By), a scientist working on a pioneering energy project, wakes up one morning to find that the technology has malfunctioned, leaving him as seemingly the only man left on earth. As Zac wanders the deserted city of Hamilton, New Zealand, hoping to find some remnant of life besides himself, his mind begins to disintegrate until fantasy and reality blur together in a heady, terrifying cocktail.
