Krishna (Hrithik Roshan) is born with magical powers - a legacy from his father, Rohit Mehra. Free as a bird, he runs like the wind... Like an eagle, he soars across rivers and mountain tops... brave as a lion, he conquers rugged rocks without fear...

Priya (Priyanka Chopra) comes into his life and becomes his world and when she beckons him to Singapore, he follows, little realizing it is destiny that has summoned him. Having sheltered him from the world, his grandmother Sonia Mehra (Rekha) reluctantly gives in and lets him follow his heart.

In Singapore, Dr Siddhant Arya (Naseeruddin Shah), the megalomaniac scientist is on the verge to change the future forever. Only one man stands between Dr Siddharth Arya and his destructive dreams, only one man has the power to block his ruthless ambitions, only one man... Krishna must become KRRISH.
