Dragnet

Upper middle-class teenagers trash a movie theater, beat up the manager and pushing a young man through a plate glass window. Sergeant Friday must get to the bottom of what is causing this to happen.

Two small boys are missing, there are blood stains on the ground and a gun meant as a Christmas present is gone.

An elderly woman is passing bad checks, but no one suspects her because she looks harmless.

A lady reports an abandoned baby at a bus depot. Officers Friday and Smith investigate, and realize her story doesn't quite hold water.

Friday leads a team in a raid on the house of a very dangerous armed robber, which results in a bloody shootout.

Friday and Smith are assigned to investigate the strangulation of an unidentified woman in a hotel room. With no leads and no clues, and no idea of who she is, they must start from scratch to find her killer.
