Of all the espionage serials by Louis Feuillade (including Les Vampires, Judex, and the Fantômas films), film historian Gilbert Adair calls Tih-Minh, “the greatest, which is to say, the weirdest, most uncanny, most dreamlike.” The six-hour epic begins as adventure-seeker Jacques d’Athys (René Cresté) returns to Nice from Indochina with his bride-to-be, Tih-Minh (Mary Harald), and a cryptic book which provides clues to the whereabouts of hidden treasure. Aided by his whimsical manservant Placide (Georges Biscot), Jacques races to decipher the mysteries of the book, while foiling the efforts of the mercenaries, kidnappers, and hypnotists eager to rob him of the treasure, and who are willing to use Tih-Minh as a pawn in their sinister schemes.
