Yasuharu Hasebe returned to direct this second sequel to his Naraneko Rokku: Onna Bancho (1970). Meiko Kaji and her all-girl Alleycats biker gang are being wined and dined by some American soldiers when a racist gang called the Eagles -- whose leader's sister was once raped by a black G.I. -- vents their hatred by gang-raping a black girl. The victim's brother leads the Brats, an interracial gang. A bloody race war ensues between the Eagles and Brats, and the Alleycats are caught in the middle. Stark and unsettling, this teen-oriented Nikkatsu Studios entry is no West Side Story, brutally dealing with both prejudice and rape by American soldiers, which had been a theme in many Nikkatsu productions since Shohei Imamura's Buta to Gunkan (1961). Television star Rikiya Yasuoka co-stars in this action film with a message. Hasebe returned later the same year with Naraneko Rokku: Mashin Animaru.
