After the trauma of his last case, and after three months spent recovering in Ireland, life is looking up for newly retired homicide detective Brian (Brick) Kavanagh. Back home in Washington, D.C., a new job shows promise when he’s asked to train criminology students in cold case techniques. Then he’s off to a whirlwind weekend in Chicago with Nora, an Aer Lingus flight attendant he’d met in Ireland. There he receives shocking news that his former partner’s wife and twin infants have been kidnapped. Brick rushes to D.C. to support Ron, the man who’s always had his back. But as days pass, Brick questions how well he really knows this man.

Cherry blossom season is Washington, D.C.’s most beautiful time of the year. But as tourists flock to the city, this year’s festivities are marred by the discovery of the naked body of a young woman floating in the Tidal Basin. Veteran homicide detective Brian (Brick) Kavanagh is assigned to the case. He’s shocked when he learns the victim is connected to another homicide, which makes the investigation very personal for him. Brick’s efforts to solve the case are thwarted by departmental politics and a rush to judgment. Convinced that justice has not been served and the wrong person is in jail, Kavanagh risks all to relentlessly pursue the truth.
