The boisterous and colorful Murphys have a lot going on in their cramped apartment above the family pub in Cork City, Ireland in 1964. The youngest of the bunch, 12-year-old Tommy, is a smart, wise-cracking kid who's starting to question family values and the Roman Catholic Church. When Tommy goes up against the ruler-wielding Sister Mary Agnes and announces that instead of being confirmed he'd rather shop around for a more "fun" religion, all hell breaks loose. A warm and hilarious look at family, growing up, and God.
