Film noir has taught audiences that bad things can happen in picture-perfect small towns just as easily as in the grimy big city, but rarely have filmgoers seen a film noir that’s also an ecclesiastical musical. Violent, propulsive, and gorgeous, Gass-Donnelly’s remarkable genre mash-up about a local police officer investigating a murder in a Mennonite community is filled with contemporary hymns and set amid a rural landscape of extraordinary beauty.

Frederick Fitzell is living his best life—until he starts having horrific visions of Cindy, a girl who vanished in high school. After reaching out to old friends with whom he used to take a mystery drug called Mercury, Fredrick realizes the only way to stop the visions lies deep within his own memories, so he embarks on a terrifying mental odyssey to learn the truth.
