J'ai épousé une ombre (1982)

Synopsis
A young woman is abandoned by her lover after she tells him she is pregnant. Deeply depressed and longing for home, she boards a train out of town. Unfortunately a terrible train wreck ensues. She survives and ends up taking on the identity of one of the dead passengers. Now comfortable and secure that her child will have some claim to legitimacy, the woman is happy. Unfortunately, her dead-beat lover shows up and promises to make trouble if she doesn't pay up. The melodramatic plot is based on a story by Cornell Woolrich and was made twice before as No Man of Her Own (1932 and 1949 respectively). In 1996 it was remade again as the romantic comedy Mrs. Winterbourne starring Riki Lake and Shirley MacLaine. ~ Sandra Brennan, All Movie Guide
