2026 17mMovie

Thriller

By day, William keeps his world neat and predictable — a quiet teacher, polite, and the illusion of control. But beneath that order lurks Trev, the violent persona that acts out everything William represses. When Killjoy, the voice of his guilt, begins calling — urging him to confess and stop the bloodshed — William’s fragile balance begins to collapse. Haunted by Pam, the woman whose twisted influence shaped his desires, William finds himself cornered between two voices: one begging for redemption, the other demanding release. As FBI Agent Harris investigates the killings linked to him, her interrogation blurs the line between his near confession and breakdown. In the end, William must choose which voice to silence — his guilt, his rage, or himself.
