The Return of the Soldier (1982)

Kitty Baldry is a haughty society queen with a tunnelled view of life. Kitty's complacency is rocked when her husband, Captain Chris Baldry, returns from the front during World War I shell-shocked and suffering amnesia, not knowing who she is, and determined for a reunion with Margaret Grey, a working class lover from his past. Kitty employs psychiatrist Dr. Gilbert Anderson to help unscramble her husband's feelings for the women in his new disoriented life, including his all-too caring cousin Jenny, but ultimately, comes to realize that the man she knew is unreachable, as dead as the past for which he pines.
