Woman's police: appointment with danger (1970)

Kagari (Akira Kobayashi), a scout and overseer of Ginza bar hostesses, receives an urgent phone call from Sawako, a hostess at the bar Rie, and rushes to Tokyo International Airport to meet her. When he arrives she is gone. At the bar he learns that Tabuchi, a steady customer, had been quite friendly with Sawako and may know something. Tabuchi claims he knows nothing and Kagari lets the matter drop. Over time Kagari learns from Takijima, a businessman, that Sawako is in a hospital in Yokohama. Takijima explains that he found her in Singapore working as a street girl and brought her back to Japan. Sawako had lost her memory after being subjected to narcotics. Kagari swears to find the person responsible.
