Jack and the team race against time to catch the Ripper while he's still on his killing spree.

Jack's growing suspicions drive Alana even closer to Hannibal, believing he is the victim of a witch hunt. Meanwhile, clues from the tree man help the BAU zero in on a location they believe the Ripper used.
