The Hum - The Secret of Ardbruichmore

The Hum: The Secret of Ardbruichmore is a hauntingly offbeat mockumentary where sound becomes ritual… and silence is never guaranteed. On a remote Scottish island, a mysterious festival pulses beneath the earth. Deep within limestone caves, locals gather to operate massive synthesizers, creating a sound said to transcend reality itself. But when tragedy strikes, the harmony begins to fracture — exposing tensions between tradition, truth, and the cost of devotion.
