A number of police stakeout posts are set up around Los Angeles, the better to capture a bandit who has been robbing hotels with a sawed-off shotgun. Alas, no sooner have Friday (Jack Webb) and Smith (Ben Alexander) begun their surveillance of the Brinton Hotel than the elusive bandit switches to holding up restaurants. It is up to a dentist named Patterfield (Robert Filmer) to provide the clue that will ultimately ensnare the bad guy. This episode is based on the Dragnet radio broadcast of April 5, 1955. ~ Hal Erickson, Rovi
