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 "Werther Effect", 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 "happiness effect". 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. 译文(2): Lea 是一个濒临死亡的年轻女孩。她开始了她最后的挑战，一个论点，寻求证据的信念，幸福可以倍增，因为可以感受到悲伤，孤独和痛苦。在展开研究的过程中，她发现了“维特效应”，一种产生负面多米诺骨牌效应的现象。她转向她的工作，一个项目，将达到相反的效果，这将被称为“幸福效应”的东西。利用折衷主义，个人主义的实验方法和积极思考的力量，联系和方程式引导她走上一条揭示最终幸福的道路。
