He was once a famous martial arts master, but now he is an unknown security guard in an old community. A bizarre murder drags him into a repeating seven-day cycle. To break the curse, he must accept the rebellious and talented young man as his disciple, regain his martial arts in time, and uncover the conspiracy. When the end of the cycle approaches, he must make a choice: return to the position of master and look down on the world, or stick to this small post and use his mortal body to protect him. Time is cyclical, but some inheritance and protection, once started, can never be looked back.
