Following a catastrophic containment failure, a group of subjects trapped inside a clinical waiting room begin responding to a mysterious frequency in terrifyingly different ways — forcing staff to determine who can still be trusted before the facility collapses into violence.

SYNOPSIS:

Following a catastrophic incident inside a behavioural observation facility, a group of subjects wait unknowingly in an isolated clinical holding area while the effects of a mysterious resonance event begin spreading through the building.

As tension quietly escalates, each individual responds differently to the unseen frequency — paranoia, emotional detachment, aggression, dissociation, obsessive repetition. What initially appears to be anxiety slowly transforms into something far more disturbing as identities begin slipping out of alignment.

Monitored by an increasingly overwhelmed facility staff, the waiting room becomes a psychological pressure chamber where perception, behaviour, and human connection begin to fracture in real time.

Coherence is a psychologically driven ensemble horror short exploring emotional contagion, behavioural collapse, and the fragile structures that hold identity together.
