In seventeenth century Amsterdam, an orphaned girl Sophia is forcibly married to a rich and powerful merchant Cornelis Sandvoort - an unhappy "arrangement" that saves her from poverty. After her husband commissions a portrait, she begins a passionate affair with the painter Jan Van Loos, a struggling young artist. Seeking to escape the merchant's ever-reaching grasp, the lovers risk everything and enter the frenzied tulip bulb market, with the hope that the right bulb will make a fortune and buy their freedom.
