Kyouji Nimura holds down the fort at an inn nestled in a hot spring area, far from the city buzz – a chill summer hideout. Enter the Hidaka Family, big shots from Tokyo, looking to kick back and relax at our spot. But hold onto your hats ’cause things take a sharp turn one evening when all hell breaks loose.
Out of the blue, the tranquility gets shattered by screams of distress. Arisa’s voice echoes through the inn as she gets pushed onto the sofa, her blouse getting a surprise lift, and her girls making an unexpected cameo, while some shady character tries to unlock the mystery of her bra. Little does she know, the whole scene’s getting caught on tape, kickstarting a twisted game by this mysterious figure, ready to drag Arisa and her fam into a dark whirlpool of chaos.
