When the doors of an old elevator close, silence becomes a witness?and a weapon.

In a city haunted by forgotten crimes, Lieutenant Dawson is drawn into a case that begins with a single sound: the mechanical sigh of an elevator in an abandoned building. Inside, he discovers a body, a letter, and a truth that refuses to stay buried.

As he follows the trail of cryptic messages, Dawson realizes he's not just chasing a killer?he's confronting the echo of his own past.
Each floor he ascends leads him closer to a revelation that could destroy everything he believes about justice, memory, and himself.
