“Sanam Teri Kasam” is an intense love story of two diametrically opposite people; Saraswathy Parthsarthy aka Saru(Mawra Hocane), a Tamilian Brahmin and her wealthy neighbour Inder(Harshwardhan Rane). While Saru is a bespectacled plain Jane, who works in a library, Inder is a cynical rebel who lives life in the fast lane.
Leading a sheltered life, under the aegis of her strict disciplinarian father, her marriage is the biggest bone of contention in her family as she is always rejected owing to her dowdy appearance and staid personality. One day, in her desperate attempt to transform herself, Saru inadvertently changes her destiny.
