该剧根据1996年前FBI探员约翰·道格拉斯和马克·欧夏克的著作《心理神探：美国联邦调查局系列犯罪破案揭秘》（MindHunter: Inside the FBI's Elite Serial Crime Unit）改编。退休后的道格拉斯深入研究犯罪心理学，美剧《汉尼拔》和《犯罪心理》中的角色刻画也参考了书中的很多案例。

Though Kevin has evidenced 23 personalities to his trusted psychiatrist, Dr. Fletcher, there remains one still submerged who is set to materialize and dominate all the others. Compelled to abduct three teenage girls led by the willful, observant Casey, Kevin reaches a war for survival among all of those contained within him — as well as everyone around him — as the walls between his compartments shatter apart.
