Im Seon-gyun lives and works in a pension located in an isolated, remote place. Something strange and strange happens in the lonely house, where her girlfriend, Oh Yu-min, doesn't look for any guests except for her coming to play. The twin virgin ghosts and the bachelor ghosts who lived in this house without having sex once declared war on the couple Seon-gyun and Yu-min. The purpose of the ghosts is to release Han, who died unfairly without experiencing sex once in their lifetime, to Seon-gyun and Yu-min. In order to fulfill the ghosts' wish that they leave Seon-gyun's house without any regrets only then when they soothe their bodies with overflowing sex, Seon-gyun spends nights and nights of extreme heat burning bones and flesh.
