Dr. Samantha (Sam) Waters
A profiler for the FBI, Sam is a brilliant forensic psychologist with a special "gift" for recreating crimes in her mind from the perspective of both the criminals and the victims. She is being stalked by the serial killer, Jack who murdered her husband as well as many other people in her life. Grieving the loss of her husband, Sam went into hiding with her young daughter, Chloe. Three years later, with Bailey's help, she took "her life back" and resumed her career as a profiler.
