Nineteen-year-old Kanae works as a poster girl in her family's bento store. Her brother, who is one year older, works in a factory. She often receives orders from her brother and knows his coworkers well. One day, she is invited to a cocktail party that her brother will also attend, and feeling relieved, she gladly accepts. However, it turned out to be a trap. Sleeping pills were put into her drink and she fell asleep, being passed from man to man.
