Sita is left on her own with the promise that her folks will return in a few days. Her grandfather also warns her of an impending thunderstorm and instructs her that if the water level rises to cover the entire island, she must seek refuge atop the peepal tree. Soon, as foretold, it begins to rain heavily. When Sita looks outside, she notes the rising level of the raging river. So she quickly packs a few important things in her trunk, but forgets her favorite doll, Mamta. She ascends the tree and waits for the storm to abate, but the water level only keeps rising. She is about to abandon all hope when a young boy in a boat rescues her. He introduces himself as Krishna and offers her mangoes to eat.
