The baby sitter is none other than veteran Hollywood tough guy Tom Neal. A private detective, Neal is hired to keep an eye on the child of married couple George Meeker and Rebel Randall. Actually, Meeker and Randall are jewel thieves, and their "baby" is their stolen loot. Neal eventually catches on when he realizes that this is the quietest child on earth. Running a scant 41 minutes, Case of the Baby Sitter was designed to be shown in tandem with another Screen Guild Productions "briefie," The Hat Box Mystery: the films were shot back to back, with Tom Neal and Pamela Blake starring in both.

Feature version of the 1945 Universal serial, JUNGLE QUEEN.

Tom Benner controls the town and the water supply. When his stooge Mayor rebels, he has him killed and replaced with Bullseye Johnson who immediately brings in Matt Canway as the town marshal. Conway doesn't carry a gun but he is soon on to Benner and out to prove that Benner has altered the survey lines to obtain the water rights.

Muggs and Glimpy, two East Side Kids in the army, return to their neighborhood, supposedly on furlough; actually, Muggs has been honorably discharged with a physical defect, but he tells no one of this. Danny, another East Side kid, is in jail because a large amount of medical supplies have been stolen from the warehouse where he works. Muggs see Spider, a new member of the gang, flashing a large amount of money around, and Muggs shrewdly turns toughie, boasting that he has a dishonorable discharge because of thievery. This leads Spider to confide in Muggs that he is the one who has been aiding in the theft of supplies from the warehouse, and he gets paid for the loot by Larry, operator of a nightclub where Muggs' sister, Milly, is an entertainer. Fingers, a henchman for Larry, kills Spider when he learns that Muggs has been let in on the operation. The police then suspect Muggs of killing Spider.
