When Harvard Law School graduate P. Cadwallader Jones (Dennis O'Keefe) bungles his first assignment in the D.A.'s office, he is next assigned the tedious job of reviewing the closed case of a crooked city official (Peter Lorre) who vanished with $100,000. of the taxpayer's money. The cold case suddenly gets hot when the money begins to reappear, and a series of brutal murders ensues. There's plenty of fast-moving action in this crime drama laced with good old-fashioned Hollywood humour.
