A family is found slaughtered in their home, yet their corpses still move; committed to the routine of their daily lives, heedless of their own grisly deaths. A local occultist commune is suspected of the crime. The bloody legacy of Catholicism and the dark roots of ancient paganism intertwine in the aftermath of a recent national revolution. Welcome to the Ireland of tomorrow.

Two ex-Gardai officers, a former Franciscan monk and a young trans woman race to determine the cause of the slayings before tensions in the community boil over and kick off a new Satanic Panic, driving the tenuous fledgling nation back into the arms of the Church.

Crom Cruach is a distinctly Irish anxiety piece about the reluctant future and repressed past of a country trying to shrug off the shackles of colonialism, wrapped in the shiny black leather of Giallo and written in a poetic style fit for the fog-shrouded mysticism of the emerald isle.
