Undercover Girl is a 1950 American crime film noir directed by Joseph Pevney and starring Alexis Smith and Scott Brady.
Christine "Chris" Miller, a newly graduated New York policewoman, vows to finish the work of her murdered detective father by infiltrating the drug ring that killed him. Under an alias, she moves into a rough neighborhood, gains the trust of Moocher, a lowâÂÂlevel addict, and uses information from Liz Crow, a faded exâÂÂmoll, to build herself a convincing cover.
Working her way up, Chris eventually reaches Doc Holmes, a doctor fronting for the gang, and Menig, a ruthless lieutenant, feeding intelligence back to Lieutenant Mike Trent while her suspicious targets and an intrusive boyfriend put her cover at risk. As suspicions close in, she helps set up a final stingâÂÂthe ring leaders are exposed and captured, her fatherâÂÂs killer is unmasked, and Chris proves herself as a capable officer in a maleâÂÂdominated force.
In a contemporary review for The New York Times, critic Thomas M. Pryor wrote: "[T]here are no surprises in 'Undercover Girl.' The film details in interesting fashion, however, how the L.A. police help Chris to win the confidence of the smugglers as a big drug buyer from Chicago. Not so interesting are the climactic moments of the melodrama when a sleazy character discovers that Chris is a cop and tips off the gang. It might be interesting, just for the sake of change, to have a police plan work out so successfully that the gang could be apprehended without discovering the identity of the undercover agent. How about it, moviemakers?"
