The Key Witness
A powerful politician secretly tortures his aide, relying on a supernatural key that whispers what it senses from others. When the aide refuses to surrender and disappears, a former soldier is recruited as the replacement. Realizing he can hear the key speak, the former soldier strikes a deal with the key to uncover the truth behind the aide's disappearance.
