Watch Full Movie Online. Teen-Age is another "exposé" film of the 1940s, cheaply made but widely distributed. In the guise of a warning against wartime juvenile delinquency, the film offers the exploitational tale of a bunch of wild, unsupervised kids at large in a small community. With nothing but time on their hands, the young protagonists become involved with petty theft, inevitably leading to some pretty serious consequences.
