When Season Twelve 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 thirteen-years-old at the time of the crime. This five-disc DVD collection includes all twenty episodes from Season twelve plus three featurettes, deleted scenes, and a gag reel.
