The Kalnagini (female black cobra) targeted a pet bird of a child for her dinner. The baby girl hits the snake with a stick for taking her bird. The Kalnagini bites the girl, the daughter of a snake-charmer, dies. The angry father plays the flute to find the Kalnagini and kills the son of the Kalnagini. Raged Kalnagini declares she will kill the son of the snake-charmer and thus will make him childless. The father rushes to Sadhu Baba, the saint. Sadhu Baba prescribes a difficult and complex way to save Mangol, the son. The snake-charmer has to feed the venom of black cobra everyday for 12 years. The boy was also given an armlet by the Sadhu Baba. The armlet must not be put off from Mangol’s body. If it is put off and one snake bites him meanwhile, from the next full moon, Mangol will be in trouble.
The snake-charmer follows the prescription. Mangol grows by drinking venom everyday. The young Mangol falls in love with Lachi, a beautiful neighbouring girl. The grandson of the head of the snake-charmers, Sheru also loves Lachi and wants to marry Lachi. He sends some thugs to kill Mangol. Mangol defeats them. But while fighting, his armlet was put off. And at that time the Kalnagini keeps her promise by biting Mangol.
