Peterson's Poi Juice is giving away a trip to Hawaii and Arnold Ziffel is chosen as the winner. When the ad agency rep meets Arnold and discovers he's not a human, he tries to disqualify the swine. Famous pig lawyer Oliver Douglas is retained to fight for Arnold's winnings.

Scheming to get Oliver to pay his way to a convention, Fire Chief Joe Carson appoints him as his assistant. Instead, Oliver finds the Hooterville Fire Department to be inept and ill-prepared. Oliver's call for improvements results in Uncle Joe being voted out and him being named the new chief.
