In India, the Gupta family have a rat problem. While the wife claims that a mongoose is the best way to control rats, the husband (for whatever reason) thinks a tame cobra is the way. So they find one of each animal and make a deal with them: whoever gets rid of the rats first stays. So the two of them try their own ways to earn their keep. The mongoose, however, tries to mess up the poor cobra's methods. Which one will stay?
