When Season 12 of Blue Bloods returns, Danny seeks the help of Maggie Gibson, a psychic medium, during his investigation into the tragic murder of a two-year-old boy, while Frank finds himself at odds with the mayor over how best to protect the city after a recent uptick in city crime.

Also, Jamie and Eddie defend Officer Witten when she receives departmental and public backlash for pulling her gun on an unarmed man during an arrest at a local deli, and Erin investigates a murder case from 1993, in which the sole witness was her boss, DA Kimberly Crawford, who was 13 years old at the time of the crime.

This 5-disc DVD collection includes all 20 episodes from Season 12 plus three featurettes, deleted scenes, and a gag reel.

The complete third season of the popular US series. Tommy Gavin (Denis Leary) is a lifesaver. Whether he's pulling survivors from fiery high-rise infernos or the twisted steel of a subway collision, Gavin takes great pride in leading the heroic but often overwhelmed firefighters of New York City's Truck Company 62. He is also a man drifting between sorrow and anger over a recent separation from his wife (Andrea Roth) and three kids, and recurring memories of comrades and other New Yorkers who fell victim to the tragedy of 9/11. Episodes comprise: 'Devil', 'Discovery', 'Torture', 'Sparks', 'Chlamydia', 'Zombies', 'Satisfaction', 'Karate', 'Pieces', 'Retards', 'Twilight', 'Hell' and 'Beached'.
