Miko Sugimoto is the leader of the Red Helmet Gang, a biker girl gang from Shinjuku who wind up in Kyoto and make a bid to take over the local girl gangs there. Successful for a short time in ruling the streets it isn't long before Miko and her crew run afoul of the local Yakuza, and are forced to turn to Reiko Ike, a ronin Yakuza girl, and sister to one of the top Yakuza in Kyoto, for help, leading to a murderous showdown at a small coastal resort.
