Two men have held up a mom-and-pop café, beating the 68-year-old owner within an inch of his life. Although one of the robbers was shot trying to escape and is currently in custody, the other is still at large, still with a stolen diamond signet ring worth $1500 in his possession. Tipped off by a car-rental agency where the ring had been offered as collateral, Friday (Jack Webb) and Smith (Ben Alexander) pursue the fugitive robber all the way to Las Vegas and Reno. This episode is based on the Dragnet radio broadcast of July 21, 1952. ~ Hal Erickson, Rovi
