O'Flynn enlists the help of a nurse at a sanatorium where Newman died. Doreen (Joan Rice) had serious misgivings on the treatment given to patients. Doreen helps O'Flynn discover that Newman is still alive, and a gang led by Dr Crabtree (Colin Tapley) are trying to sweat the information out of Newman...
A complicated plot with various double crosses and changes of identity. The film is fairly light and breezy in tone, despite a certain amount of murder and brutality... all in the crisp, chipper nature of an early 1950s British film.
