In the heart of a desolate city stood St. Cecilia’s Cathedral, abandoned after a devastating fire claimed the lives of its devoted choir. Years later, Ethan, a sound engineer fascinated by urban exploration, entered the charred remains of the cathedral to capture its acoustics for a personal project. As he set up his equipment, he began to hear faint hymns echoing through the halls. Intrigued and unnerved, Ethan followed the ethereal melodies to the main sanctuary, where he encountered apparitions of the choir, their faces obscured by shadows, singing a requiem that seemed to beckon him to join their eternal performance.
