Shot in the seedy Boyle Heights district in Los Angeles, InSight follows Kaitlyn, an ER nurse who while tending to a young stabbing victim, Allison, is accidentally electrocuted by the defibrillator that was being used to save the woman's life. Almost immediately she starts to experience the victim's memories. Kaitlyn turns to family, friends, and the police, but no one takes her seriously, so she takes it upon herself to solve the crime - as the terrifying visions threaten her sanity. Ultimately, Kaitlyn teams up with detective Peter Rafferty and weaves her way through the victim's past in an attempt to discover the brutal truth about the murder and herself.
