When Lieutenant Lauren Kelly is exiled to the Homicide Cold Case Unit at the DA's office, she knows her superiors are sticking her there as punishment until she can quietly retire. That way, no one can claim they discriminated against the only trans detective in Donn County. Even though Lauren has enough on her plate already-a teenage daughter struggling with Lauren's transition, an ex-wife Lauren hasn't gotten over, a former detective father with Alzheimer's-she starts looking into the murder of Sherry Darling, a trans sex worker and Lauren's former high school classmate. As Lauren looks deeper into Sherry's case, she finds evidence of a cover-up with far-reaching implications that may or may not be tied to the reason her mother left.
