1x17 - The Forgotten

A mysterious young man knocks on The Forgotten Network's door with a most unusual request -- 'help me find my identity.' After a violent assault put him in a coma, John Doe has no recollection of who he is. During the investigation, the team tracks the Doe's past to a world of crime, where a member of their team is nearly killed. But who is John Doe? Why hasn't anyone come forward to identify him? And was it this dangerous lifestyle that led to John Doe's assault.
