The summer’s most-anticipated new drama begins Wednesday when movie star Halle Berry fronts Steven Spielberg’s “Extant.”

The 13-episode series begins at 9 p.m. Wednesday on CBS (Time Warner Cable channels 11 and 1011).

Set in the future -- bathroom mirrors double as TVs -- “Extant” is a mystery thriller about female astronaut Molly Woods (Berry) trying to reconnect with her family after returning from a year in outer space.

Her experiences in space -- she comes back pregnant despite being alone -- lead to events that ultimately will change the course of human history. Extant is the opposite of extinct, after all.

The supporting cast includes Goran Visnjic (“ER”) as Molly’s inventor/scientist husband, John; Pierce Gagnon as their son, Ethan; Hiroyuki Sanada (“Helix”) as a wealthy tech genius and Michael O’Neill (“Bates Motel”) as Molly’s boss. Sanada and O’Neill regularly play baddies, so you can guess what they are here.

All the questions you have from watching the trailers, especially about the Woods’ son, Ethan, are answered in the pilot. Of course, the first episode will leave you with more questions -- which will make the drama one of the most compelling (or maddening) of the summer.

Berry’s character drives the story. The Oscar winner is a good choice for the role. She plays Molly strong and smart, yet vulnerable, which is why Molly’s in her predicament.

And while “Extant” is a mystery, you can expect a commentary of sorts on freewill, which is at the heart of the storyline about artificial intelligence. Just how important is freewill? We’ll soon find out. Grade: B
