Jules and Leontine Grogrande (played by William Wilton and Bridget Yamber) run a bakery when one day one of their regular customers, Ali Dubh the Arab (played by Daniel Freitas), has a strange request. Three of Ali’s countrymen are chasing him and trying to retrieve the vial he is holding. Ali asks the bakers to hold onto the vial which holds the Great Elixir. A drop of the Great Elixir can grant increased health, strength, and longevity. Leontine is reluctant to take charge of the vial until Ali also gives her a vial to cure her rheumatism.
