Midnight Lady is a low-budget variation of the evergreen stage and screen meller Madame X. In one of her rare starring roles, Sarah Padden is cast as Nita St. George, the hard-boiled owner of a big-city speakeasy. Unexpectedly, Nita is reunited with her daughter Jean (Claudia Dell), who has been raised to believe that her mother is dead. When Jean is accused of murdering her no-good boyfriend, Nita selflessly takes the blame, never letting the girl know that she is really her mother. Just when it looks as though Nita will be convicted of murder, Jean is tricked into a confession -- but as it turns out, she didn't do it either! Unfortunately, this not uninteresting poverty-row drama is laid low by bad camera work and uneven acting.
