Sue Shihomi, often a co-star with the better known Sonny Chiba, stars in the title role in SISTER STREET FIGHTER. Shihomi plays Tina Long, a female karate master looking for her missing brother. She discovers from the police that he was an undercover agent working with them to bust a heroin ring, and she agrees to assist the cops in order to find him. But to defeat the onslaught of bizarre hitmen who come gunning for her, she must enlist the help of Sonny (played by Chiba), another karate master. Tina and Sonny race to find her brother and stop the drug kingpin, leaving a trail of broken and bloodied bodies in their wake.
