The Rug cop is a seriously fun homage to Japanese cop shows from the 70s. Officer Genda (Fuyuki Moto) is a rebellious police man with a somber heart and a secret weapon: a flying toupee. Bounced from station to station by the upper brass, he ends up with a group of abnormal detectives with names such as as Shorty, Fatty, Big Dick, the Old Man, and Mr. Handsome.
