州政府为节省财务开支，计划把分别由拉萨雷和毛瑟所领导的两所警校撤销一所，为了从生存竞争中胜出，两位校长各施所能，毛瑟在州长与学监面前大拍马屁，并且暗中在拉萨雷警校中安插了两名内线；而拉萨雷则召回了昔日优秀学生担任教官助阵，于是马哈尼（斯蒂夫•古根伯格 Steve Guttenberg 饰）、黑巨人高塔、泰克布雷等六人再次回到警校
毛瑟为了获胜，将看不顺眼的学员赶到拉萨雷处，很快，一班古怪学员汇聚拉萨雷警校：从上一集中出现的懦弱眼镜男和流氓头子，到精通空手道的日本交换生应有尽有
马哈尼等人必须在短期内将学员们打造成合格的警察，但这个任务并不简单，除了学员本身的素质限制，毛瑟一伙也在暗中破坏 斯蒂夫·古根伯格Sgt Carey Mahoney莱丝利·伊斯塔布洛克Lt Debbie Callahan博卡·格德斯维特Cadet Zed (as Bobcat Goldthwait)大卫·詹姆斯·艾略特Cadet Baxter #2 (as David Elliott)查尔斯·布巴·史密斯Sgt Moses HightowerDavid GrafSgt Eugene TackleberryMichael WinslowSgt Larvell JonesMarion RamseySgt Laverne HooksArt MetranoCmndt MauserTim KazurinskyCadet SweetchuckGeorge GaynesCmndt Eric Lassard, Midcity Police Academy Shawn WeatherlyCadet Karen AdamsScott ThomsonSgt Chad CopelandBrant von HoffmanSgt Kyle Blanks (as Brant Van Hoffman)Bruce MahlerSgt Douglas FacklerEd NelsonGov NeilsonDebralee ScottCadet FacklerLance KinseyCapt Proctor (Cmndt Mauser's flunky)Brian TochiCadet NogataAndrew ParisCadet Bud KirklandGeorge R RobertsonChief HurstGeorgina SpelvinThe hookerDavid HubandCadet HedgesR Christopher ThomasCadet Baxter #1Arthur BatanidesMr KirklandJack CreleyMr BellowsRita TuckettMs TylerChas LawtherMr DelaneyLyn JacksonMs ClickMary Ann ColesMrs HurstSam StoneCabbieGrant CowanMr Miller (line-up room victim)Bruce PirieLine-up room copDoug LennoxAxe murdererTeddy AbnerTommySusan DeRyckBasketball playerMarcia WatkinsCadet SarahPam HyattSarah's motherFran GebhardWoman at cafe Les NirenbergMan with cigar Gloria SummersMaidFred LivingstoneElderly man Gladys O'ConnorWoman at phone boothPaul Maslansky、Donald L West杰瑞·帕里斯Jack RoeGene Quintano、Bill BannermanRobert FolkBud MolinFern Champion、Pamela BaskerTrevor Williams、Dennis DavenportKen Brooke演职员表资料来源：网站评分参评人数统计截止日期豆瓣7 125892023-12-11
