Sergeant Joe Friday and his partner are called in on a robbery investigation in which witnesses give police one particularly memorable clue: the suspect sports a conspicuous moustache. What follows is classic Dragnet, as the detectives sift through descriptions, question witnesses, and methodically work the leads in an effort to identify their man. [yidio.com]
