Matt Stifler, the younger brother of the legendary Steve Stifler, who made it big as Hollywood porn-producer and shamelessly ignores the idolizing kid brother, may claim the title of Stifmeister as his heritage, but even for his horniest mates he's little more then a bad joke. When Matt alone gets caught red-handed for a prank with the school band's instruments, present high school counselor Sherman 'Sherminator' finds great pleasure in taking revenge on him for the misbehavior Steve excelled even worse in, so instead of expelling the little prick, he condemns him to take part in band camp at Great Oaks, where Jim Levenstein's still understanding dad is filling in for the feared problem counselor. As there are plenty of girls in the competing bands, Matt hopes to turn his (mis)fortune around by smuggling in camera equipment including a robot to shoot saucy, clandestine material for his counterpart to Steve's hit video "Girls Gone Wild", an at least as 'revealing' Bandies Gone Wild. Matt's nerdy, yet also horny roomie Ernie was originally confined to the closet, but is promoted to assistant-producer when he proves himself an invaluable technician. Things get complicated as Matt becomes romantically involved with Elyse, his own school band's director, whose ambition is to beat haughty five-fold winner Brandon Vandecamp -son of a famous, rich father- as band music composer and thus win a good shot at a scholarship for an exclusive music school. For her sake Matt turns musician (on the trivial triangle by her decree, bagpipes in surprising scenes) and proves his leadership skills, but courting a 'decent' girl just doesn't square with voyeurism... 《美国派4》：乐队夏令营。额 我情不自禁地快进了。不错的青春喜剧派对。一塌糊涂。人员大换血、恶搞依旧。美国派4(番外篇)。我的收看簿：《美国派4集体露营》。失败的续集。一部很喜欢的电影。其实这是一个青春期教育片。 硬条家族的一员——麦特（泰德•希根布尔克 Tad Hilgenbrink 饰）即将升入高三，他对家族前辈们的业绩羡慕不已，立志也要拍出一部刺激的个人电影作品，但是麦特的为人教人难以欣赏，嚣张的他把欢送毕业生的表演变成了一场闹剧，校方为了惩罚麦特，要求他加入仪队夏令营，如此麦特和担任仪队指挥的青梅竹马伊丽丝（阿莉尔•凯贝尔 Arielle Kebbel 饰）再次相聚，但伊丽丝厌恶麦特的种种恶作剧早已与其反目成仇。 夏令营对渴望得到奖学金的伊丽丝意义重大，但是麦特却只顾用买来的各种偷拍设备为自己的香艳小电影搜集素材，或是与夏令营的明星队员作对。玩世不恭的麦特渐渐体会并理解了周围人群的追求，他与伊丽丝的裂痕也在渐渐弥合，这次夏令营会成为麦特的成长之旅么？
