Special Agent Stevie Winters has recently transferred into the violent crimes unit of the FBI's Cleveland Division, a boys club where her presence is not welcome with open arms. On her second day, Stevie is thrown into her first homicide investigation when a case from the past comes back to haunt the unit and a serial killer they never caught starts killing again. The switch from cyber crimes to violent crimes will come as more than just a culture shock as Stevie finds herself in the crossfire between a crazed suspect and the sociopathic murderer, catapulting her into the undesirable position of becoming the next victim.
