The CW has released the official synopsis for "Who Are You?," the midseason premiere of Arrow in which Oliver wakes up in a SoHo bar where a policeman knows his name.

Still reeling from the loss of Felicity's boyfriend and the apparent return of Laurel Lance from the dead, Team Arrow will redouble their efforts to track down Prometheus, the serial killer who has been terrorizing Star City as a way of getting back at Oliver, apparently for having killed his father as "The Hood" back in the show's first season.

There's also a new quest set up to find the person who trained Oliver (likely Talia Head/al Ghul); Diggle's storyline is headed for a trial date; and a new ally will apparently join the fray in the quest to clear his name. You can check the solicitation out below.
