The returning soldier is amnesia victim Alan Bates, who remembers nothing of his life before suffering shell-shock--not even his long-term marriage to snooty Julie Christie. Spinsterish Ann-Margret, who has long harbored a fondness for Bates, hopes to take advantage of his memory loss. But both Christie and Ann-Margret are challenged by a third woman, Bates' childhood sweetheart Glenda Jackson. Poor Bates deals with all of this by not dealing with it. A fairly faithful rendition of the Rebecca West novel on which it is based, Return of the Soldier ambles along at its own languid pace to a inconclusive conclusion.
