CBS is lifting the veil on its mysterious summer thriller Extant.

Below is the first significant promo for the drama series, which stars Halle Berry as an astronaut who returns to Earth and then … things happen. That’s about all we’ve known for months about the Steven Spielberg-produced series. But here we see Berry as Molly Woods (yup, floating in space!), then she has some sort of strange encounter with something while on her mission. Later she arrives home to discover she’s pregnant, and her son is saying creepy, potentially prophetic things. Could Extant be like a sci-fi Rosemary’s Baby?

Check out Berry in zero-g, all Gravity-style (minus Sandra Bullock’s booty shorts) in this first trailer for Extant. The series premieres Wednesday, July 9.
