From his home in Ilium, N.Y., optometrist Billy Pilgrim (Michael Sacks) narrates the tale of how he came to be "unstuck in time." Kidnapped by aliens and living in comfort with his assigned mate, B-movie starlet Montana Wildhack (Valerie Perrine), Billy experiences the events of his life in random order, flitting between his past as an American prisoner of war in World War II, to his humdrum middle-class life in the present-day, to his future as a zoo curiosity on the planet Tralfamadore.
