In desperate need of a fresh batch of police officers, the newly appointed Lady Mayoress of a crime-plagued metropolis lowers the bar for the recruitment process. As a result, all types of misfits start flocking into Commandant Eric Lassard's prestigious Police Academy, and the leader of this assortment of pariahs is Carey Mahoney: a light-hearted, devil-may-care young rebel. But now, there is no turning back, and to make matters worse, the autocratic martinet, Lieutenant Harris, can't wait to see them quit. Then, a full-scale riot breaks out, and the inexperienced but dauntless cadets will have to put their training to good use. Do they have what it takes to be law-enforcement officers?
