Passion (1986)

Sylvia and Cora Miao play two widowed mothers, best friends and confidants who spend their days reminiscing about times past. Over the course of a lazy weekend afternoon, the two women conjure memories of Cora's husband, his life, his death, and his passionate affair with Sylvia. A series of wistful flashbacks reveal the sometimes touching, sometimes painful circumstances around the women's deep friendship with one another, and their love for the same man.
