Twenty years ago Megan had her heart broken. Not that she would ever admit it. As a surgical resident in New York City, she stitched up a wounded young cop named Tommy Sullivan who was shot during a drug bust, and a passionate love affair began. It ended just as tempestuously when he cheated on her. Reeling from this betrayal, she returned to Philadelphia vowing never to be hurt again. She built a highly successful career and an equally successful marriage. Or so she thought. She never appreciated how the demands of her career were taking a toll on her personal life until her husband divorced her and she lost custody of their then seven-year-old daughter Lacey. Adding to this emotional trauma, Megan soon suffered a physical one, a car accident that left her with a condition called paresthesia -- random attacks of numbness and cramping of her hands. Tragically, this condition failed to manifest itself until Megan's first trip back to the operating room. She lost control of her instruments and her patient died on the table. Megan's life as a neurosurgeon was over. Two years into her new life as a Medical Examiner, Megan has rechanneled her genius and personal tenacity into solving the medical mysteries of the dead and uncovering who was responsible and why. Along the way she has tried to repair some of the emotional damage she caused to her daughter and to others close to her. She may never be done, but she has arrived at a place of relative peace with herself. And then Tommy Sullivan walks back into her life. After a long career in New York City Detective Tommy Sullivan has relocated to Philadelphia where he has the unenviable job of teaming with Megan to solve homicide cases. Their personal history will animate every investigation they are uncomfortably forced to work on together. Starting with an action-packed two-part episode, Season Three will grab you with higher stakes and bigger thrills and chills as Megan, Tommy and their respective colleagues work to chase down killers before they kill again. And with each passing case, as the personal tension between Megan and Tommy evolves into mutual respect and even hints of their old personal attraction, Megan will start to wonder if she should risk opening herself up to this man again. The answer will come as they tackle the biggest case of Megan's career -- indeed the biggest mystery of Megan's entire life: Did her father really commit suicide, or was he murdered?
