Where to Watch Nalladhoru Kudumbam (1979)

Raja and Vanisri marry to fulfill a grandfather’s dying wish, but their relationship soon unravels after a tragic misunderstanding involving one of Raja’s former lovers. A missed call, a child's death, and broken trust lead to their separation—each raising a son alone, determined to prove that a child can thrive without the other parent. Years later, both sons grow up to be bright and successful, but their own marriages bring unexpected heartache. As history begins to repeat itself, Raja and Vanisri must come together again—not for themselves, but to mend what their sons are now losing.
