Nobody Knows (2020)

In the pulsating heart of the regional investigation unit, Detective Cha Young Jin relentlessly pursues the elusive 'Stigmata' serial killer, a phantom from her past that left an indelible mark when it mercilessly claimed her friend's life 19 years ago. This pursuit, both a relentless quest for justice and a desperate attempt to heal old wounds, has led Cha Young Jin into a solitary existence, her life echoing with the silence of solitude. The only exception is her unique bond with Go Eun Ho, the innocent-eyed son of her downstairs neighbor. This young boy, drawn to her like a moth to a flame, helps her with household chores, his purity a stark contrast to the harsh world she confronts daily. However, a veil of mystery descends when Eun Ho ventures into a forbidden room, a move that sends ripples through their tranquil relationship. Lee Sun Woo, a man of complex connections as the former chairman's son and current chairman's brother in law, finds himself as Eun Ho's homeroom teacher. A peculiar feeling gnaws at him as he senses something amiss with Eun Ho, further weaving the intricate web of lives tangled in secrets and lies. Nobody Knows is a thrilling, suspenseful journey through a labyrinth of crime and connections, a hypnotic dance between the hunter and the hunted, where every turn could lead to a shocking revelation or a deadly end.
