童年，成长经历，家庭背景，社会关系，创伤…… 我们不断追溯与求索犯罪者的动机，探寻其中最幽微的喜怒哀乐，不是为了设身处地地同情、乃至于原谅他们，不是为了给罪行以开脱的理由，不是为了跪服于所谓人性的复杂，不是为了反思社会矛盾，更不是为了把自己也异化成怪物—— 我们只是在给自己、给仍然对这个世界抱有期望的人——寻找一个公正的交代。

Mort Rainey, a writer just emerging from a painful divorce with his ex-wife, is stalked at his remote lake house by a psychotic stranger and would-be scribe who claims Rainey swiped his best story idea. But as Rainey endeavors to prove his innocence, he begins to question his own sanity.

A ticking-time-bomb insomniac and a slippery soap salesman channel primal male aggression into a shocking new form of therapy. Their concept catches on, with underground "fight clubs" forming in every town, until an eccentric gets in the way and ignites an out-of-control spiral toward oblivion.
