The Vertical Ray of the Sun (Mua he chieu thang dung)

Three sisters and their brother, prompted by the anniversary of their mother's death, meet at the eldest sister's cafe. They are obviously a close family, sharing their most intimate secrets without guilt or fear. Or so it seems. Involved in relationships at various stages of development, they all hold back disturbing secrets of sexual complicity, most dramatically the youngest sister, Lien, who seeks a husband just like her brother Hai (with whom she has a complex and ambiguous relationship). When Lien investigates an aspect of their mother's life previously unknown, the family is thrown into tumult. Her discoveries threaten the idealized memory of their parents that has kept the family fiercely connected."
