Barry McKenzie is a die-hard Aussie who is sent to England by his family, accompanied by his eccentric aunt Edna Everage. Loud-mouthed, beer-crazy Bazza encounters a totally alien culture and becomes embroiled in a series of strange vicissitudes, from being pressured to marry the unattractive daughter of an aristocratic-but-penniless family to being kidnapped by a group of hippies.
