Famed detective Dandy Sashichi tries to solve who's behind the serial murders of six beautiful women under the aegis of local showman Ibaragiya. The film opens with the sextet humiliating a respected painter's portraits of them, driving the man to a suspicious suicide. Later, while celebrating his son's impending marriage into a wealthy family, Ibaragiya releases six pigeons from a pleasure boat, each with a rolled up drawing of one of the beauties tied to their legs. He offers a cash reward to whomever recovers the pictures, but they instead become death notices of which of the six are next to die.
