High concept noir which must have felt close to home for those who lost their men in WWII. A broke, pregnant woman is cruelly given a ticket out of town by the feckless dad. After the train crashes she is assumed to be the expectant wife travelling with her husband to meet her rich in-laws for the first time… Because they are both dead and unrecognisable.
So it’s a classic mistaken identity scenario adapted from a Cornell Woolrich story. Mother (Barbara Stanwyck) and baby are taken into a secure, loving home while the brother (John Lund) of the dead man falls in love with her. And the anxiety of being exposed gradually unravels the imposter’s nerves. Especially when the real father turns up for a spot of blackmail!
Stanwyck is at least 20 years too old but still effective and arouses maximum sympathy for an archetype familiar from depression melodramas. Lund is a little humdrum as her suitor, but his steadfast dependability is clearly the answer to her prayers. It's a dreamy domestic noir with a gloomy expressionist look.
And director Mitchell Leisen is good at the suspense. It's necessary to buy into the crazy concept… but this is a classy production with a fine cast, which conveys an emotional truth. And maybe even offered empathy for the widows of war, left behind without economic support at a time when it was improbable for a woman to survive alone.
