The plot of "Star Trek: Discovery," the new series in the space franchise, has been kept under wraps. But showrunners Aaron Harberts and Gretchen J. Berg are finally opening up a bit about the initial storyline that viewers will see when the show debuts on CBS All-Access this fall.

The show centers around Sonequa Martin-Green's First Officer Michael Burnham, who is the first human to attend the Vulcan Science Academy. She also has a notable mentor in Spock's father, Sarek (James Frain).

Her life has "been completely planned until she makes a very difficult choice that sends her life on a very different path," Harberts told Entertainment Weekly. "When we meet her, she's the First Officer on the Starship Shenzhou [captained by Philippa Georgiou, played by Michelle Yeoh].

And Burnham's choice that we're alluding to is most difficult choice you can make — it affects her, affects Starfleet, affects the Federation, it affects the entire universe. That choice leads her to a different ship, the Discovery [helmed by Captain Lorca, played by Jason Isaacs] and there we begin what Gretchen and I call our 'second pilot.'"

And since Burnham is the first lead character who isn't a captain, she'll provide fans with access to different parts of the ship.

"The advantage to her not being in charge of the bridge right now is we get to tell stories from a very different point of view," Berg explained. "It's a fresh feeling because we're not on the bridge all the time."

"Star Trek: Discovery" premieres September 24 on CBS with two episodes. Those and all remaining episodes will stream weekly on CBS All-Access.
