Brian lands in the town of Munty. Fortunately, there's a pub where he meets the owner, Herman (a former warrior) and his handful of regulars: Barbara (a questionable soothsayer), Steg (an armchair revolutionary) and Howell (a deranged wizard).
Herman relaunches the pub, new look, new drinks and an advert in the local paper. But when Brian collects the wrong barrel from the docks the entire gang end up trapped inside.
Brian is being forced to perform in a travelling circus, run by the sadistic Feffenhoffer (Steve Coogan). Barbara and Steg set out to rescue him while Herman accidentally traps a fairy.
Brian pitches for a job in the pub while Herman helps an old warrior friend. Barbara finds herself in charge of the Munty Pet show, which Howell is attempting to fix.
Brian introduces popcorn to Munty. Barbara dreams of becoming one of the famous Munty Clack Dancers. Howell makes a truth potion for Slasher Morgan with disastrous results.
