The Star Trek universe is getting another addition to the long-running franchise with the upcoming CBS All Access original series Star Trek: Discovery.

Set before the events of the original series, with Kirk, Spock et. al., Discovery follows the crew of the titular Federation starship, helmed by Captain Lorca (Jason Isaacs), from the perspective of its First Officer, Michael Burnham (The Walking Dead’s Sonequa Martin Green; now we know why they killed her character, Sasha, off).
