Unable to suppress the urges in her daily life, she finds solace in tight bondage images and videos discovered online. Her greatest admiration lies with a renowned rope master known for his work in SM shows and photo books. When her husband leaves for a week-long business trip, she sees this as her only chance and resolves to meet the master in person. Driven by the masochistic thrill of finding pleasure and release through being tied up, her journey into this forbidden world is about to begin.
