Detective Frank Smith (Ben Alexander) gets word that four vicious hoodlums who have cut quite a swath of crime and terror in San Francisco are headed for LA. Setting up a stakeout in a seedy hotel, Smith and his partner Joe Friday (Jack Webb) must contend with a drunken desk clerk (Peter Leeds) while waiting to pounce upon the four outlaws. Based on the Dragnet radio broadcast of March 14, 1950, this is one of the most readily accessible of the original black and white TV episodes, and no wonder: one of the thugs is played by a young and very swarthy-looking Leonard Nimoy (complete with pencil mustache!)
