Belum's nightmares force him to confront the cruelest question: what if becoming human means losing the thing that makes you matter? The movie finally lets you inside his head instead of just watching him fight monsters from the outside. You get something the series couldn't quite land, a man questioning whether saving his sister's life was worth the cost of his own.

Two years after the events of the TV series, investigator Sonia is still hunting for the humanoid monsters, and her search brings her to Draco Chemical, a drug company. There she meets Belum Eyesburg, a man who is the exact double of Bem, yet leads a quiet, normal life with a wife and family. Meanwhile, Belo battles a dark organization by himself so that Bela can have a regular life as a human girl. Once Belum has crossed paths with Sonia, nightmares begin to haunt him. He starts to doubt who he really is, and the calm family life he has built starts to come apart.
