A triple bill from the 1930s heyday of tough guy movies. In 'Bullets or Ballots', Johnny Blake (Edward G Robinson) needs to go undercover to investigate racketeering. After Police Captain Dan McLaren becomes police commissioner, he knocks him down convincing rackets boss Al Kruger that Blake is sincere in his effort to join the mob. However, 'Buggs' Fenner (Humphrey Bogart) thinks Blake is a police agent and he wants to find out the truth. In 'San Quentin', Captain Stephen 'Steve' Jameson ( Pat O'Brien), the penitentiary's new yard captain, wants to make those years a time of rehabilitation rather than punishment. Problems begin when Joe Kennedy (Humphrey Bogart), the brother of his new girlfriend May, is sentenced to the prison for robbery. When Jameson tries to separate lawbreakers from hardened criminals, bad guy Hansen tries to stir up trouble by telling Joe about Jameson's interest in his sister. An inmates' strike and a scripture-quoting con who swipes a rifle are among the troubles Jameson faces and Red is another as he reverts to his old ways and makes a violent break for freedom. In the comedy 'A Slight Case of Murder', Edward G. Robinson stars as a tough but good-hearted bootlegger. When Prohibition is repealed, Robinson faces a financial crisis as his beer tastes so awful that no one wants to drink it legally. As an additional headache, Robinson is under scrutiny from the Law, which is waiting to slip the cuffs on him for the slightest infraction. He arrives at his rented Saratoga mansion with his wife (Ruth Donnelly), daughter (Jane Bryan) and adopted son (Bobby Jordan), only to discover that a killer has left four corpses in his bedroom. Robinson and his stooges are forced to hide the bodies before his future son-in-law (Willard Parker), who happens to be a cop, tumbles to the dilemma. Based on a stage play by Howard Lindsay and Damon Runyon.
