The story of your police force in action. A bandit has held up a hotel with a sawed off shotgun, and it’s up to Joe Friday to catch him. Joe and his partner, Frank Smith are on the scene, and as the uniformed cop heads out. The hotel clerk relates the facts of the robbery.

The man demonstrates his new tech, a transistor radio with ear phone. Imagine that! a radio without tubes! And you can just carry it around and listen to your favorite shows through an ear piece, wow!

After a description of the man, the detectives track down the clues. A photo line up is prepared, and Friday returns to have the hotel clerk pinpoint the robber. More hotel robberies occur, and all by a man with a sawed off shotgun. Though the investigation continues, no new info has been turned up.

A new clue comes in from a mom and pop hotel owner. A woman with a very sad marriage arrangement. Friday stakes the place out, thinking it may be the next logical place to be hit. A call comes in, that takes Joe and Frank to the site of where the night’s robbery went down. The robber seems to have switched from hotels to all night cafes.

When a tooth is knocked out in this latest altercation, the cops get busy interviewing dentists. Joe has his man, and knows the reason why he skipped the hotel that was staked out. All that’s left is to move in and gather the hard evidence to tie their man into the crimes.
