When they aren't performing their churchly duties, the altar boys at the parish are a gang of hell-raising
delinquents. After quietly serving the host or gently swinging incense during Sunday Mass, the Altar Boy Gang is out smoking cigarettes, drinking beer, breaking windows and selling drugs. The Altar Boy Gang follows the characters who work at and attend a Catholic church in an urban Canadian city. A priest starts to question his faith. A parish mother expects everyone around her to be as holy as the pope. Altar boys make drug drops in the confessional booth.
