The Black Tulip(1970)

The Black Tulip is a historical drama set in 17th-century Haarlem, where the city offers a fortune to whoever can cultivate the legendary black tulip. Gardeners across the Netherlands compete fiercely for wealth, prestige and glory, driven by memories of the devastating Tulip Mania that gripped the nation decades earlier. Young nobleman Cornelius van Baerle stands on the brink of victory when he's suddenly imprisoned in Loevestein Castle on false charges.
