Considering that the film was made by tiny PRC, it sure could have been a lot worse! I know this isn't exactly a glowing endorsement, but it is better than about 75% of the films I've seen from this so-called 'Poverty Row' studio! Now I know this isn't going to get you to rush to see it, BUT if you are bored you can download it for free from the link on IMDb.
The film begins with mobsters muscling in on the produce business. When people refuse to play along with them, 'accidents' happen! The problem is that although the police can catch the individual gang members, the identity of Mr. Big is uncertain--and eventually calls for some undercover work.
As another reviewer pointed out, the message from this film was very patriotic and was emphasizing the importance of price controls and self-sacrifice during time of war. Unfortunately, the film just doesn't make that point very interestingly and the boss' sudden change of heart made zero sense at all---leading to a very unsatisfying finale. Still, the acting wasn't bad and it wasn't bad...just not all that good either.
