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; having been told that Catholicism is the only sure path to the kingdom of the Lord, Pete decides to convert a Jew to Catholicism in order to improve their standing in the afterlife. Hoping to find a likely candidate, Pete begins visiting a nearby synagogue, where he gets to know Rabbi Jacobson, who responds to Pete's barrage of questions with good humor. Pete also makes friends with the Rabbi's son, Danny, who is about the same age; when he learns that Danny is seriously ill, he decides Danny would be an excellent choice for conversion. When the priest at Pete's church informs Pete that all will be tested before they pass the Pearly Gates, he sets up a mini-decathlon and puts Danny in training as he attempts to reshape his spiritual thinking. Pete's parents aren't sure just what to make of Pete's new summer project, and as they become acquainted with Rabbi Jacobson, they share their perspectives on the unexpected trials of parenting. 信念是进入天堂的唯一途径。介绍。 1976年，芝加哥。 大部分三年级学生都在过他们的暑假，8岁的彼得却因在校犯事，被恶修女警告已迈向地狱之门，除非他在这个暑假修成正果。彼得决定在区内广行善事，虽未能「招揽」信徒，却渐渐与7岁犹太男孩丹尼结为好友。彼得向丹尼说只要信奉天主教就可得救赎，后来得知丹尼患上白血病。确保丹尼能上天堂成为彼得当前使命，两人踏上探索人生、宗教和哲理之途……
