Haru Shibasaki, a rescue team member dispatched to the disaster area. In the extreme life of evacuation, the rescue that began with a sense of justice gradually transforms into a dedication called "sexual treatment". In the shelter where sweat, tears and bodily fluids are mixed, she offers her pure body, even when she is consumed by desire, she spreads her legs to accept ejaculation in order to save others - rescue and pleasure intertwine.
