Miracle on Main Street (1939)

On Christmas Eve in the Spanish quarter of L.A. police try to arrest a couple running a shady floor show. Hiding in a church, the girl finds an abandoned baby and uses it as cover to escape capture. Thus she finds herself with a baby she is becoming ever more fond of, a helpful doctor himself too fond of the bottle, and a husband who has disappeared. Dare she try and change her ways and keep the child?
