A mother and a son. A goddess and a prince. A curse and an oath. A river whose course will change the fate of the world.

Ganga, joyful goddess of the river, serves as caretaker to the mischievous godlings who roam her banks. But when their antics incur the wrath of a powerful sage, Ganga is cursed to become mortal, bound to her human form until she fulfills the obligations of the curse.

Though she knows nothing of mortal life, Ganga weds King Shantanu and becomes a queen, determined to regain her freedom no matter the cost. But in a cruel turn of fate, just as she is freed of her binding, she is forced to leave her infant son behind.

Her son, prince Devavrata, unwittingly carries the legacy of Ganga's curse. And when he makes an oath that he will never claim his father's throne, he sets in motion a chain of events that will end in a terrible and tragic war.

As the years unfold, Ganga and Devavrata are drawn together again and again, each confluence another step on a path that has been written in the stars, in this deeply moving and masterful tale of duty, destiny, and the unwavering bond between mother and son.
