新的未来，每个人的心理状态、性情都可以被量化。
从情绪倾向到犯罪行为，一切都被记录下来并用作引导每个人走向美好生活的指南：不仅追求幸福，而且实现幸福。不用说，公众很高兴开始量化他们的日常生活。这种决定个人心灵道德的价值观的总称，通常被称为“心理通行证”。
该值的一个组成部分是犯罪系数，它最终是代表个人犯罪潜力的数字。为了打击那些试图破坏现状的人，由执法者和督察组成的侦探们协力维护和平与秩序。前者负责抓捕嫌疑人，后者负责监督和指挥下属同事。毕竟，执法者拥有很高的犯罪系数。然而，由于其犯罪性质，他们可以更好地了解其他犯罪分子的动机，从而使他们能够嗅出嫌疑人并逮捕真正的肇事者。但由于其犯罪背景，督察需要对每个案件做出冷静、明智的判断。最终，MWPSB 的所有成员都必须谨慎行事，在面对社会所面临的最糟糕情况的同时保持自己的心理健康。
第一分部的侦探们怀着正义之心，侦破每一起案件，直面人性的丑恶真相。
但是，接下来会发生什么呢？
In the new future, everyone's mental state and disposition can now be quantified.
Everything from emotional tendencies to criminal behavior are recorded and utilized as a guideline to lead everyone to the good life: not only pursuing happiness, but attaining it. Needless to say, the public was excited to begin quantifying their everyday lives. The general term for this value, which determines the morality of an individual's heart and soul, is commonly known as the Psycho-Pass.
One component of this value is the Crime Coefficient, which is ultimately a number that represents an individual's potential to commit crime. In order to combat those who attempt to disrupt the status quo, detectives work in tandem to maintain peace and order, composed of Enforcers and Inspectors. The former is tasked with apprehending suspects, while the latter oversees and commands their subordinate colleagues. After all, Enforcers possess high Crime Coefficients. However, because of their criminal nature, they can better understand what makes other criminals tick, allowing them to sniff out suspects and arrest the true perpetrators. But because of their criminal background, Inspectors are needed to provide a calm and sound judgement to each case. Ultimately, all members of the MWPSB have to walk a fine line, maintaining their own mental health while facing the worst that society has to offer.
With justice in their hearts, the detectives of Division 1 tackle each case, confronting humanity's ugly truths.
But, what lies ahead?
