Blackie (Chester Morris) and the Runt (George E Stone) are about to head off to Florida when Blackie receives a call for help from a fellow ex-criminal (or is he?) Arthur (Lloyd Corrigan) asks Blackie to take $60K from his safe in New York and take it over to California.
Somehow this is mixed up with the theft of a valuable diamond, Inspector Farraday (Richard Lane) of course thinks Blackie has stolen the diamond and so follows Blackie to California and gets mixed up in a complicated tale of blackmail and stolen goods...
Still early in the series but the series is now hitting high gear. A fast-paced story with plenty of swerves and action packed into a short running time. Good humour and performances add to make this an excellent film.
