A bunch of crooks use a comic, featuring stories penned by Felix H. Wilkinson (Alastair Sim), to pass on coded messages for robberies.
When some of the comic's readership, a bunch of East End boys, discover what's going on, they go to the police. The local constabulary, however, are no help, and so the plucky lads set out to foil the robbers themselves...
Directed by Charles Chrichton.
