Plot:
An English engineer and inventor, William Crackford, is visited in his workshop by a messenger, who tells him that the famous alchemist Alcofrisbas is interested in selling him a powerful talisman. Arriving in Alcofrisbas’s mysterious laboratory, where they are attacked and confused by magically moving and transforming pieces of furniture, Crackford and his servant John explain to the alchemist that they hope to make a high-speed trip around the world. Alcofrisbas promises to make the trip possible. With the help of his seven laboratory assistants, Alcofrisbas makes a batch of large magical pills for the engineer and demonstrates that, by hurling a pill upon the ground, Crackford can have any wish gratified. Crackford, in his excitement, does not read the terms of the contract he is asked to sign, and so remains blissfully unaware that he has just sold his soul to the Devil. When Crackford and John leave, “Alcofrisbas” resumes his true identity—Mephistopheles—and his “assistants” are revealed to be the Seven Deadly Sins.
