An eclectic group of characters set sail on Captain Lansen’s leaky cargo ship in an attempt to escape their various troubles. When a violent storm strikes, the ship is swept into the Sargasso Sea and the passengers find themselves trapped on an island populated by man-eating seaweed, giant crabs and Spanish conquistadors who believe it’s still the 16th century.
