Pete, an eight-year-old Catholic boy growing up in the suburbs of Chicago in the mid-1970s, attends Catholic school, where as classes let out for the summer, he’s admonished by a nun to follow the path of the Lord, and not that of the Devil. Perhaps taking this message a bit too seriously, Pete decides it’s his goal for the summer to help someone get into heaven – by trying to convert a Jew to Catholicism.
