14岁的Gwang Ho(李在应饰)正值高中生，除了被青春期的问题所困扰之外，对外界的政府风波爱理不理，而且与母亲Malsoon相处也不太融洽，他并不喜欢母亲因推销化妆品的工作而作出浓妆艳抹的装扮，反而看上了与他们同住的租客－当护士助理的Eun Sook…… 与此同时，Gwang Ho认识了一位经常跟着他的奇怪朋友Jae Myung。 尽管有一天总统逝世，他继续对政治冷感的态度，反而他更加关心收到的一封印着「尼克逊总统被刺杀」的匿名连锁邮件。因此他唯有将此信再传送给他的妈妈、Eun Sook和Jae Mung，由于三人没有再传送这封连锁邮件，从此恶运却随之而来……

Absorbed in his thoughts, Gwang-ho is oblivious of the news of the presidents death and the picture of the new president replacing the late president in his classroom. Gwang-ho receives a letter of luck and starts sending it to people around him. As those people start vanishing, Gwang-ho is racked with guilt, suspecting the letter of luck is the cause of their disappearance.
