The Houseboat 1961

Three men and the woman who comes between them. The men, all struggling in early adulthood, share a floating bamboo hut on the river. The woman Penh is the daughter of the boys' landlord, and the likely fiancee of law student Jane. The brash, alpha-male Kaew is a Muay Thai fighter. And there's Rin a singer. All the guys have an eye on Penh, and Penh clearly adores the attentions of them all.
