"Tropical Nights" - A young violinist Alma comes to Simbali with an orchestra led by conductor Zangiacoma, hired for a series of performances in the Schomberg hotel. Both the conductor Zangiacomo and Schomberg are persecuting Alma with their love. One evening, when Alma is, as usual, forced to sit by the guests in the cafe and encourage them to spend as much as possible, she meets Heyst who arrived that evening from his island Sourabaya, where he lives in solitude, away from the world and people. He takes Alma to his place on the island.
