Undercover Girl is the second noir movie directed by Joseph Pevney after the interesting Shakedown. A policeman is killed and his policewoman daughter (Alexis Smith) searches for the killer and his drug organisation, she meets all kind of weird and deranged people, the best being Royal Dano really creepy as a desperate wolf looking for a nasty thing to do, crawling along walls with his tie with a naked girl (he makes me think of Jack Elam we see in another script writer Harry Essex noir title, Kansas City Confidential). The all cast is great, giving an anguishing atmosphere to this too rare movie.
