Cantinflas is a down on his luck but affable shoe shiner that learns that his ''compadre'' has died in an accident. His friend's widow, Leonor (Flor Silvestre) is unable to raise her child, Chavita, so she leaves the kid with Cantinflas so she can go to Guadalajara, Jalisco in order to seek help from her parents. In the first days, Cantinflas goes to work in Chapultepec and Chavita catches a ball that some other children are playing with, and almost ends up in a fight with the owners of the ball. Cantinflas calms down the child by promising he will bring him a new ball.
