Hriday, a naughty little boy, is unthinkingly cruel to animals. He goes his merry way till a terrible crime causes him to be turned into a Thumbkin with no prospect of return to the human world.
Now, he is at the mercy of the very same animals he has wronged, and is desperate to make amends. But all the animals are happy with his situation! Finally, the pet lame swan of the family takes pity and Hriday is wafted away on his creaky wings to the Himalayas in search of Lord Ganesha who can save him.
Little does Hriday realize that this will be the beginning of the strangest adventure in the worlds of mice and men, Gods and demons, hate and love, and better understanding . . .
