After nearly two years off the air, USA's Mr. Robot will return for its final season beginning Sunday, October 6.

The thriller from creator Sam Esmail (Homecoming) sees Elliot (Rami Malek) and Mr. Robot (Christian Slater) return for more cyber-antics as Season 4 picks up where Season 3 left off. Will Elliott's decision to hit "send" on the email that could reverse 5/9 do more good or bad?

Set during the 2015 Christmas holiday, the show will say "Goodbye, Friend" in a fast-paced season composed of 13 all-new episodes. When Elliot and Mr. Robot get back to work, prepare for a story filled with "answers, hacking and blood."

Echoing the finality conveyed in the simple key art below, the teaser hints at a wild last chapter.
