Show premieres July 2
The teaser runs 25 seconds and will reveal almost nothing to you about the show, so no spoiler alerts are necessary.
What CBS has said so far about the show is that “Extant” is a mystery thriller about a female astronaut trying to reconnect with her family when she returns after a year in outer space. Her experiences lead to events that ultimately will change the course of human history.
Series bows July 2 at 9 p.m.
