Kishanlal marries the beautiful Lachchi, but the day after the wedding, he leaves on business for five years. When Kishanlal reappears only a few days later, Lachchi is delighted, but this new Kishanlal is in fact a spirit who has taken the form of Lachchi's husband, after having seen her by chance and fallen in love with her. Four years later, the real Kishanlal returns and the townsfolk must determine who is who.
