Yoon Jae-keun invests the action movie with a novel spin as a man with considerable combat  skills finds himself trapped in a seemingly never-ending cycle of body swapping. Ian (Yoon Kye sang) wakes up at the scene of a car crash to find he has been shot. With no recollection of his  identity, he finds his situation even more bizarre when he discovers that twice a day his spirit  swaps bodies. Dealing with each new physical form, he suspects that the people he occupies  might be connected in some way, all leading back to the work of a shadowy pharmaceutical firm.  But the more he investigates, the more danger he and his many forms find themselves in.
