The comically inept graduates of the Police Academy are back to save the day! A heinous crime ring known as the Wilson Heights Gang, headed by the mysterious Mastermind, has unleashed the worst outbreak of lawlessness and mayhem the city has ever known ... not only endangering the lives of innocent citizens, but also threatening something even more sacrosanct--the city's real estate values. Meanwhile, the eternally uptight and painfully inept Lt. Harris--suspecting that a spy lurks within the precinct walls--creates his own havoc. In a dilemma this grave ... circumstances this desperate ... only one team of crime busters can come to the rescue--those fast-firing, wacky characters from the Police Academy.
