Factual and almost documentary-like in the beginning, this is the CSI of the 1940s, featuring on-site filming of the FBI's actual crime-solving tools and laboratory. But soon we find a character with which to identify with -- an FBI agent (Mark Stevens) infiltrating a city gang which has already committed two murders in the town. But there is a mole in the local police department and the crime boss is getting hot on our man's trail. Will our FBI spy beat him to the punch? There's a symbolic twist in the end, and a good sense of increasing pace. I enjoyed this one a lot!

Haven't really seen the CSI of that era, so it was refreshing. Also god damn people did not like windows in this movie
