During his honeymoon, the irrepressible Larry Burton is dragged off into the jungle by a large-sized male baboon and is presumed dead - eaten by apes. However, defying all odds, Larry survives and, after many comic-strip-type adventures, returns home to re-establish himself as head of the household - little realising that his wife, Sally, has married the staid and conservative Boyd Flatt during the intervening ten years, and that she is now the mother of a bright and lively nine year old daughter. Larry's return home causes considerable upheaval and consternation for the family - not least being his subsequent attempts to woo a reluctant Gabriella, his former sister-in-law, who had taken a distinct dislike to him prior to his disappearance and is still definitely opposed to the idea of getting to know Larry on a more intimate basis.
