In Manhattan, Thana is a timid and mute woman that works as a seamstress in the fashion industry and spends most of her idle time at home. One night, she gets raped in an alley while going back home after hours and when she arrives at home, she gets raped again by another criminal. However, she reacts and brings down the assaulter with a flatiron. The disturbed Thana loses her sanity and uses the .45 caliber pistol to shoot men on the streets of New York. She dresses suggestively and roams the streets alone, wreaking vengeance upon anyone who tries to take advantage of her. Eventually, her secret life spills over into her regular life in the fashion industry.
