Trust Korean directors to come up with interesting time based storylines. This time, one of my favourite romantic directors has decided to come up with a thriller. The story about a copy and a school teacher who are 30 years apart yet can communicate with each other through their dreams. When they realize that the woman they love is in danger, they have to come together in their dreams and figure out a way to protect her. This is an interesting thriller that keeps you engaged until the end. The climax is very good.
