The grownups involved in East Side Kids concern three men from the slums on the lower East Side of Manhattan. Leon Ames is a cop, Dennis Moore is in the rackets, and Dave O'Brien is in the death house. In fact he's taking a rap for shooting a cop in a job that Moore did. It's the code of the streets not to squeal and O'Brien would rather get the chair than do that so Ames is going to have clear him the hard way.
In the meantime Moore is now involved in a counterfeiting racket and uses a group of kids from the old neighborhood to spread his bogus currency. One of them is Harris Berger who is O'Brien's kid brother. In the meantime O'Brien and Berger's sister Joyce Bryant is being romanced by Ames as well.
For those of us who are used to seeing the clowning antics of Leo Gorcey and Huntz Hall this film is strictly on the serious side. There were no fatalities usually with the Gorcey/Hall group, but this one has a few. It's a nice B picture drama with a good pace to it.
