Pity poor police captain Dugan (Harry Carey). As if he hasn't got enough trouble with the green recruits that Headquarters continues saddling him with, he also has to solve a series of high-profile jewel robberies. Enter brash rookie cop Danny Blake (Dick Foran), whose know-it-all attitude drives Dugan right up the proverbial wall. Even more irritating are Blake's newfangled "scientific" crime-solving methods, not to mention the fact that the newcomer is sweet on Dugan's pretty niece Kathleen Burke (June Lang). Eventually, of course, Blake and Dugan work side-by-side, shoulder-to-shoulder to catch the head of the jewel thieves in the act (to reveal his identity would spoil the fun, though it isn't hard to figure out). ~ Hal Erickson, Rovi
