great moment

The biography of Dr. W.T. Morgan, a 19th century Boston dentist, during his quest to have anesthesia, in the form of ether, accepted by the public and the medical and dental establishment.

Sir Edward Pelham, married to a Romani Russian, fears that his daughter will follow in her mother's footsteps and arranges a marriage with her cousin, whom she does not love. During a trip to Nevada with her father, she meets engineer Bayard Delavel, who saves her life when she is bitten by a snake; when her father finds her with Bayard in his cabin, he forces them to marry. Believing that Nadine does not love him, Delavel leaves her and prepares to sue for divorce. A lost film.

The film follows Gabriel Angel (Rakie Ayola), a young Caribbean aviator who falls in love with the forger Duncan Stewart (Jonathan Pryce) on her journey to England. Stewart is pursued by his nemesis Rex Goodyear (John Hurt), and the group are supported by Dr Angela Bead (Vanessa Redgrave) and Miss Gwendolyn Quim (Dorothy Tutin), retired missionaries who become lovers during the voyage.
