Toshimaru Murai

Two maniacs go on a rape spree, brutally battering their victims with a baseball bat repeatedly before raping them and then battering them again until their vicitm is dead (hence the title of the film)... but this time they picked the wrong girl.. (drama.net)

Four horny lunatics have a van and the will to rape, assault, and humiliate women. They drive around and pick women to satisfy their wanton lust. Two women are captured and the sex begins, but that is not where it stops. At different locations, the four exert themselves and go into the realm of torture and pain. Then there is vengeance.
