The two mother and son, who depend on each other, have been living a hopeless life. One day, however, all that changed. Trevor's sociology teacher Eugene Semente (Kevin Spacey Kevin Spacey) assigned a special homework assignment to make the world a better place.

Mimi launched an all-Oscar lineup for the film: Kevin Spacey, who won an Oscar for best actor, plays the leading actor, while Helen Hunt, who won an Oscar for best actress, plays child star Haley Joe Osment as Trevor, the little hero who makes the world a better place.
