Eureka (1983)

Arctic prospector Jack McCann, after fifteen years of solitary searching, becomes one of the world's wealthiest men when he literally falls into a mountain of gold in 1925. Years later, in 1945, he lives in luxury on a Caribbean island that he owns. But his wealth brings him no peace of mind as he copes with Helen, his bored, alcoholic wife; Tracy, his dear, but headstrong, daughter who has married a dissolute, philandering social-climber; and Miami mobsters who want his island to build a casino. His life is entangled with the obsessions of those around him with greed, power, and debauchery against a background of occult symbolism.
