A Pit (1967)

A reporter, Nagako Kita, is fired for writing about police corruption. To make money, she hides while a weekly magazine publishes photos of her, and offers a prize to the person who discovers her. A group of three bank embezzlers, So Yamamura, Eiji Funakoshi, and Sotoji Mukui, employ Mukui's younger sister Fukiko as a fake employee at the bank and plan to make her disappear when the real woman appears again and blame the crime on her.
