A man who is presumed dead awakens on Ethan's examination table and walks off, which sends the team's investigation scrambling off in another direction. Megan's startling DNA discovery from the crime scene also throws things for a loop.

A famous equestrienne who ran a vocational program for prison inmates is murdered, and the prime suspect is a convicted felon and former drug addict. Meanwhile, Megan's ex-husband is upset to learn that she took Lacey to a crime scene, but Megan becomes equally peeved when she finds out that Lacey is being dragged along on her father's vacation with his new girlfriend.
