His career as a western star having recently come to an end in the US, Wayne Morris is the star of the British The Dynamiters. Morris plays an American insurance investigator, trying to get the goods on an elusive gang of London thieves. The crooks invariably wipe out all evidence by dynamiting the places they've plundered. While snooping around, Morris takes a break in a nightclub, where a musical number called "Soho Mambo" is thrust upon us. One nice side effect of The Dynamiters was that, by working in London, Wayne Morris was available to co-star in Stanley Kubrick's prestigious antiwar drama Paths of Glory.
