The lead character, New York Detective Jim Dunbar, was blinded in a shootout when his partner failed to cover him. He could have retired with a full pension after his injury, but instead fought to remain on the job, determined to prove he still has what it takes and be an asset. Now, following his reinstatement, he is assigned to a new precinct where he intends to take on cases with the help of his guide dog, Hank. In the premiere episode, the newest victim of a serial killer is found brutally murdered. Detective Karen Bettancourt, who had been working for eight months with Detectives Tom Selway and Marty Russo on the case, now finds herself re-assigned by the precinct's Lieutenant, Fisk, to partner with Dunbar on the investigation of a stolen car. Just as a resentful Bettancourt begins to think she's being completely marginalized in this new dynamic, Dunbar discovers that the stolen car may be connected with the string of murders.
