While attending the cremation of his mother's remains, London bank manager Henry Pulling (Alec McCowen) meets eccentric Augusta Bertram (Maggie Smith), a woman who claims to be his aunt and announces that the woman who raised him was not his biological mother. She invites him back to her apartment, where her lover, an African fortune teller named Zachary Wordsworth (Louis Gossett Jr.), is waiting for her. Shortly after she receives a package allegedly containing the severed finger of her true love, Ercole Visconti (Robert Stephens), with a note promising the two will be reunited upon payment of $100,000 ($433,000 in 2013 dollars).
