What would you do if you ran into your perfect double, your "doppelgänger" - somebody who looks exactly like you? That is just the starting point for this supernatural thriller that explores the duality of nature, and the conflict that arises when we cannot come to terms with both sides of our personalities. When meek scientist Michio Hayasaki comes face to face with his own doppelgänger, he is at first terrified, believing that when this happens, you will die. Resisting at first, Hayasaki eventually leans to deal with his double, who, though physically identical to him, is frighteningly opposite in nature. The doppelgänger pushes Hayasaki further and further into accepting the opposite side of his own nature, as his life starts heading into a downward spiral that can have only one conclusion.
