 When a veteran cop is murdered in the line of duty, Jordan leads the police and vengeful Detective Eddy Winslow - Max s former partner - to a possible suspect. But after the shooter dies in police custody, Garrett must launch a coroner s investigation to see if Det. Winslow went too far while making the arrest. Elsewhere, Garrett opts to forgo his annual Christmas feast with his ex-wife, Maggie and join Lily for a Thai dining experience, angering his daughter, Abby, while Trey worries if Nigel s invitation for a weekend on the ski slopes also includes a slalom under the sheets.
