Newlyweds Brendan and his American wife Nicole live in Cork, Ireland, but their marriage is not working. Nicole is far more adventurous than quiet Brendan, and she's ready to call it quits. Brendan comes up with a scheme to rob a safe with his friends to impress her, but things don't go smoothly. When the money winds up at a Catholic school going through financial problems, the friends try to get it back. In doing so, they face a complication they never anticipated: the anger of an Irish nun.
