When LAPD detective Michael Gideon and his police-dog partner Sirius are assigned to the Special Cases Unit (SCU), Gideon knows their work lives will be anything but ordinary. SCU gets the cases no one else wants, the unusual and bizarre crimes that need special handling and special investigators. When a high-school student is found crucified in a local park, Gideon and Sirius must face up to the gruesome tableau and the motivation behind the murder. Complicating matters is a nightmare from their past, the scars of a terrible fire that nearly cost them their lives. The blaze left Gideon ravaged by PTSD — and yet somehow imbued him with an eerie prescience that gives him unusual insights into the crimes he investigates.
