The sea that has been frozen all winter has thawed, but it has also revealed the evil hidden in the deep sea.
Ten years ago, a shipwreck took away Carl's mother, leaving him with lifelong disabilities and nightmares. The strange mountain-like black shadow in the deep sea became a lingering shadow for him.
As an adult, Carl entered the forensic department as an intern, and his quiet life was broken by a series of bizarre murders: people with strange deaths, strange wounds, and crazy colleagues. . . The truth about the shipwreck ten years ago gradually emerged.
Karl is trapped in a desperate situation, burdened with the pain of bereavement and old wounds. When facing a desperate situation, how will he make a final reckoning with the evil from the abyss?
Purpose: Facing the unknown existence, the protagonist and his father did not succumb to the temptation of evil and fought with flesh and blood, highlighting the dignity and courage of human beings who would rather die than surrender even if they are disabled and in desperate situations.
