It stars Hong Kong Phooey, the “number one super guy” who travels about the city in his “Phooeymobile”, fighting crime with the aid of his manual “The Hong Kong Kung Fu Book of Tricks”. The stories begin at the police headquarters, where Hong Kong Phooey's alter ego, Penry, works as a mild-mannered janitor under the glare of Sergeant Flint ("Sarge"). Also at the police station is Rosemary, the telephone operator, who has a crush on Hong Kong Phooey. After Rosemary gets a call and explains the crime, Penry runs into a filing cabinet and (always getting stuck) transforms himself into Hong Kong Phooey.
A less than competent super-hero, Phooey’s crime solving is done either by fortunate blunder or, most likely, with the help of his faithful companion, Spot the police cat. Hong Kong Phooey is a respected superhero who always gets full credit for Spot’s success.
