The programme stars Karl Howman as the mysterious Mulberry, a man who appears at the household of a cantankerous spinster, Rose Farnaby, and applies for a position as her manservant.
Surprisingly for a Grim Reaper, Mulberry has a sentimental, even comical, side with a love of life and laughter that moves him to dedicate himself to ensuring that the sullen Miss Farnaby's last days on Earth are happy, using his role as servant to put his plans into motion.
He appears in most episodes as a mysterious figure (billed as "The Stranger") in a black hat and dark clothes, urging Mulberry to get on with the job.
Ambiguous references are made to where Mulberry and his father 'come from', and what kind of beings they actually are, but these issues are not resolved in the show due the cancellation of the series.
Additional locations include a former Little Chef (now a Travelodge) in Saint Leonards in Hampshire, and the Westbourne Shopping Arcade in Bournemouth.
