The series follows Morgan Gillory, a single mother of three who works as a cleaner at the Los Angeles Police Department. Morgan has an IQ of 160, classifying her as a high-potential intellectual (HPI). When she unexpectedly solves a complex case using her unorthodox thinking and keen observational skills, she is recruited as a civilian consultant for the LAPD’s Major Crimes Division. There, she is partnered with Detective Adam Karadec, a disciplined and methodical investigator whose by-the-book approach often clashes with Morgan’s intuitive and unconventional methods.
A subplot follows Morgan’s use of LAPD resources to investigate the 15-year-old disappearance of Roman, the father of her daughter Ava.
