Proctor, Call a Doctor!

When Harris is injured and hospitalized, Proctor becomes Acting Captain for a day, and is forced to deal with a hostage crisis. The mayor has been kidnapped by Mr Sleaze, who wants his goons released from prison. The chase leads our heroes to an amusement park, where they scurry through loads of roller coasters, dodgem cars and haunted houses, in hot pursuit of the thugs.
