As part of a secret society dedicated to the belief that modern alchemy can be uncovered through old folk songs, a young couple unwittingly enters a world of supernatural danger and otherworldly powers after they listen to the wrong song sung by the wrong person.

With its disorienting energy and fresh spin on Irish folk horror, writer-director Paul Duane’s first feature instantly casts a hypnotic and unsettling spell over you and never loosens its grip, leading to an unhinged finale that’s unlike anything else out there. —Matt Barone
