When you die, your soul gets recycled, or more specifically your soul energy. Yes, recycled and used for another living being. Just like in chemistry where you cannot create things out of thin air, human essence is reused again and again. But what if someone died with regrets or hatred? Then that soul energy that is reused is malicious. Refusing to accept that they’ve died, the soul will do anything to live again… even kill. Kang Dae-mi is shocked when she witnesses someone’s death.

Can Dae-mi save them before time runs out and what was only a vision turns to reality?
