How Often Is Sometimes? (1982)

They are two women in love with one man. One is the wife, the other is the mistress. And between them, the man whose love and time they share. But even the most discreet of affairs can be laid open, and the most submissive of wives can lose her patience. Vilma Santos, Hilda Koronel and Dindo Fernando lend their thespic talents to this moving tale of love, betrayal and retribution.
