In the aftermath of Catherine's suicide, Detective John Cardinal outwardly accepts the evidence that she took her own life, but when he starts to receive taunting greeting cards blaming him for her death, he begins to question the suicide.
The series is set inside the bubble of Silicon Valley, amid misguided corporate cultures, moony innovation labs and cutthroat private high schools. It is centered around a rift between a self-appointed “inventor of the future” tech CEO and his self-serving “performance psychologist”, who are engulfed in a scandal sparked by the exploitation of personal data.
