On a southern island, deviant women fully unleash their sexual desires, engaging in shameless sex driven by pure instinct. Men and women lose themselves in frenzied, trance-like mating, unable to control their animalistic urges. Minds numbed and senses dulled, they spiral into madness, entangled in aggressive girl domination, slavery, and swapping, completely surrendering all reason. Whispering, "We're utterly insane now," they give in to their instincts and spiral out of control.
