July 20 (UPI) -- CBS All Access debuted a new trailer for its upcoming show Star Trek: Picard at San Diego Comic Con on Saturday.
The sci-fi drama is slated to start streaming in early 2020.
In one scene, Picard recalls how nearly two decades earlier, his friend Data sacrificed himself to save Picard's life.
He opens a drawer to reveal the dismembered android that was once Data.
"I really tried to belong here, but it never truly felt like home," Picard is heard saying in voice-over as he stares at the sky.
A young woman arrives later and asks Picard for help, prompting him to head to a city where he reports the incident to officials.
The clip ends with Picard back commanding the crew of a ship and saying, "Engage."
Stewart played Picard in the TV series Star Trek Next Generation, which initially aired 1987-94, as well as in several Star Trek movies.
