As soon as Chief Inspector Banks goes on vacation, problems begin in his police department. An unregistered gun is found in his daughter's friend's bedroom, and an innocent man dies while trying to seize the weapon. Meanwhile, Banks's replacement (and not entirely indifferent to him), Inspector Annie Cabbot, unexpectedly finds Banks' daughter Tracy at his home along with an unknown young man, and he opens fire and wounds Inspector Cabbot. Looks like Tracy's hooked up with the bad guy. Now the father and his subordinates have to risk their lives to rescue her from the clutches of a crazed criminal.
