"Blake" (Patrick Holt) is determined to go to extraordinary lengths to bring down a gang that are peddling stolen goods in London. He starts off by staging the robbery of a jeweller's. Of course he is swiftly apprehended, and whilst in prison befriends gang member "Joey" (Michael Balfour) and they concoct an escape plan together that will enable him to infiltrate the smugglers on the outside and identify their kingpin. Once out, he attracts the suspicions of henchman "Mack" (Michael Brennan - where on Earth did the accent come from?) but the support of the boss's savvy girlfriend "Joan" (Sonia Holm) before it all all comes to a head over some fur coats resulting in a rooftop chase... It's a bit on the procedural side, but the photography of post-war London is interesting and Dora Bryan adds little joie-de-vivre as only she could in these easy going, but largely forgettable B-features.
