Eugene Simonet, an emotionally and physically scarred social studies teacher, challenges his young students to devise some type of philanthropic plan and put it into effect. A young boy, whose own life is far from rosy, takes the assignment to heart and invents the "pay-it-forward" philosophy, which encourages paying back favors in advance. The whole town embraces the boy's concept, and random acts of kindness become a community pastime. Though celebrated by acquaintances and the media, the boy struggles at home with his alcoholic mother, and the only one who recognizes his lonely fight is Eugene Simonet.
