Sonequa Martin-Green confronts a group of hostile Klingons in the first trailer for CBS's "Star Trek: Discovery."
As the crew comes across an unknown object at the edge of Federation space, Martin-Green and Yeoh must decide what to do when they come into contact with Klingons.
"Starfleet doesn't fire first," Yeoh says when discussing how to deal with the threat. "We have to!" Martin-Green replies.
"Star Trek: Discovery" takes place 10 years before the original 1966 "Star Trek" series.
The cast also includes James Frain as the father of Mr. Spock, Anthony Rapp, Doug Jones, Rainn Wilson and Jason Isaacs who was announced as the captain of the U.S.S. Discovery but is missing from the trailer.
"Star Trek: Discovery" is set to debut this fall with the first episode airing on CBS before moving over to the network's video on-demand and live-streaming service, CBS All Access.
