Love in Sampan is the tale of an unfortunate young woman named Kiu. As she explains in the opening narration, she has known three men: Wah (a boy who worked in her family's shop), Chuen Wong (a local gang boss whom she is compelled to marry) and Man (a university student). But when she accidentally witnesses her best friend, Kim, fooling around with a man, Kiu's sexual curiosity is truly aroused ... and begins to grow.
