 Keith Tobin s wife Sally and daughter Debbie think he is a salesman, but he is actually the hotly-pursued "Polka Dot Bandit". Would-be blackmailer Ed Merchant discovers Tobin s polka dot mask, gun, and stolen money, and demands half his "take" on all future jobs. Tobin lures Merchant to a remote area and murders him, but his body and car are discovered by Officer Dennis. When Dan Mathews finds Tobin s address in the car, he goes to the Tobin home and exposes Tobin as a thief and murderer in front of Sally. Tobin flees in his car, unaware that Debbie has concealed herself in the trunk to "hide" from Dan and Officer Dennis. A tense pursuit ensues, with Tobin unaware that Debbie is in the trunk and the officers forced to hold their fire to avoid hitting the terrified child.
