James Cagney and Bette Davis star as a less-than-scrupulous private detective and the woman he loves--who has just left him for aneven less scrupulous employer. Jimmy Corrigan (Cagney) is jealous when his operative and sweetheart, Joan Martin (Davis), goes to work for his seemingly upper-crust rival Charles Wallingham (Alan Dinehart). But Corrigan discovers that Wallingham is just as crooked as Corrigan; he's just better at concealing it. Now--even as Corrigan tricks an eyewitness into marrying a guilty client so she can't testify incourt--he must prove Wallingham is a crook to win Martin back. Directed with panache by Michael Curtiz, the result is a fast-pacedcomic delight, and a superb showcase for the first teaming of its two incandescent stars.
