Mamta is the story about the universal theme of motherhood. What happens when a young surrogate mother is told that her child was still born? What happens to her when she comes to know, a year later that it is actually alive, but she realises that it is not in safe hands? What happens when a woman conspires surrogate pregnancy just out of greed of wealth? What happens when a unhappily married man falls in love with the mother of his surrogate child...?
