This is the first police academy movie that is missing Officer Mahoney (Steve Guttenberg). To replace him, they added Matt McCoy (who Seinfeld lovers will recognize as Lloyd Braun) as the nephew of Cmndt. Lassard.
The group travels to Miami Beach to a police convention where Lassard is to be given the Police Officer of the Decade.
Lassard is kidnapped and the film ends with the typical police academy chase and rescue.
It's a mildly entertaining film. It's certainly not the worst in the Police Academy series. If you've seen any of the others, you know what to expect.
