A spring day in the heart of the Tower of London, a final favor is demanded...
We are in the year 1536 and the French executioner, Jean Robo, has been summoned by Henry VIII to behead his wife, Anne Boleyn.
However, on the eve of her execution, Robo makes a promise to the unfortunate queen. He promises to bury her six-fingered hand, the symbol of her rumored magical abilities, at a sacred crossroads.
Through a relentless pursuit, battling between galleys loaded with slaves, experiencing the hallucinations of the mystical fire of St. Anthony, and ending up in the castle of a Messiah of the Apocalypse, Jean struggles to keep his promise.
