　　Lea is a young girl on the brink of death. She begins her final challenge, a thesis that seeks proof in the belief that happiness can be multiplied, as can the feelings of sadness, loneliness, and misery. Unfolding the research, she discovers the quot;Werther Effectquot;, a phenomenon that creates a negative domino effect. She turns to her work on a project which will achieve the opposite effect, something which would be named the quot;happiness effectquot;. Utilizing an eclectic, individualistic approach to experimentation and the power of positive thinking, connections and equations lead her on a path to uncover ultimate happiness.
