Mind Control Co. is a special enterprise known for renting out hypnotic items, existing more as an urban legend than a widely recognized reality. Only individuals harboring intense emotions such as deep resentment, jealousy, or anger are permitted to use these hypnotic items for a period of three days. While there is no cost involved, a special counseling session is required to measure the depth of one's emotions and confirm their eligibility. This recorded footage documents a teacher who, having been betrayed by a student, borrows a hypnotic item to unleash her vengeful feelings. Hidden within this scenario is a mysterious power that allows complete control and possession over another during the limited span of 72 hours.
