Sunny is an incorrigibly naughty boy who likes to have his way in school as well as at home. He is often punished and sent by his teacher Naina to Principal Popatlal but it has no effect on him.
When the principal writes a letter of complaint against him for his parents 10 sign, Sunny happily forges their signature, and gets away with it, too. One day, Popallal calls Sunny's parents and tells them exactly what Sunny has been up to. The parents become strict with him and Sunny's life then becomes difficult.
He prays to Lord Krishna to give him powers to control his teachers and parents. The Lord grants him his wish. Alter that, Sunny leads a happy life, both, in school and at home. However, he gets caught copying by somebody who is not his teacher and thus he can't control that person -and so, he is rusticated from school.
But luckily the Lord Krishna story is his his dream and when he wakes up he tries to reform.
