Frank Drebin (Leslie Nielsen) has retired from Police Squad and lives a basically happy life with his wife, Jane Spencer-Drebin (Priscilla Presley). It remains "basically happy" because police work has been Frank's meaning of life, and he feels unhappy about not being able to legally take on criminals anymore. Additionally, Jane tries to push him into siring a child, but Frank does not have the courage to go through this yet. It comes as a blessing to him when his old friends Ed Hocken (George Kennedy) and Nordberg (O.J. Simpson) come by and ask for his help in an investigation. The Police Squad has caught wind that a well-known bomber named Rocco Dillon (Fred Ward), who is currently incarcerated, has been hired by a terrorist (Papshmir, known from the first movie) to conduct a major terrorist act against the United States.

However, the first part of the mission – by pure accident – proves to be extremely taxing; Jane becomes frustrated both at Frank's sudden unwillingness to engage in his marital duties and the suspicion that he is doing police work again, and storms out of the house.
