A group of rogue priests from the Augustine Interfaith Order of Hellbound Saints operates under the radar, taking on missions to exorcise powerful demons. This unconventional order, known for indulging in sins such as drinking, smoking, and cursing, believes that living sinful lives gives them an edge against the forces of darkness. Led by the gruff and seasoned Father Angus, the team includes the stoic Larry, the tormented Stephen, the eccentric Macon, and the unpredictable Elizabeth. They operate out of a rundown church in Brooklyn, always prepared to dive into the most extreme situations to protect humanity from demonic entities.

When a particularly dangerous demonic force threatens to break through to the mortal world, their unconventional methods and sinful lifestyles are put to the ultimate test. The team faces internal strife as their unorthodox approach begins to clash with the severity of their mission. As they delve deeper into the bizarre and deadly occult occurrences, they uncover terrifying truths about the nature of their enemy. With their lives and souls perilously on the line, the ragtag team must confront not only external demonic threats but also their own personal demons, testing the very limits of their faith and fortitude.
