A father's heart is as big as the whole world, it is said. A disabled cycle trishaw driver who has lost a leg is lovingly raising his two children alone as their mother ran away.

When the little son fell ill and had to go to the hospital, the desperate father could not afford the money for medical treatment. He now has to take on other jobs, collect rubbish from the street or donate blood. Meanwhile, a young, committed female doctor is taking care of the little boy, whose father, in turn, cannot understand that she is doing this "man's job". Based on a true story!
