CBS bet big on the new series from Steven Spielberg’s Amblin Television, Extant, picking it up straight to series (13 episodes) back in August.

Now, Amazon is announcing that Amazon Prime Instant Video will be the exclusive streaming home for the series, which is slated to debut this summer.

All new episodes of Extant, which will premiere on CBS in June, will be available to stream by Amazon Prime customers 4 days after their original network airing.

If this model sounds familiar, that’s because Amazon struck the same deal with CBS for last year’s hit Under the Dome, based on the Stephen King novel of the same name. It had plenty of success in the streaming realm – Amazon says that Under the Dome was “watched by more customers than any other TV season on Prime Instant Video in 2014.”

“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” – according to its official description. Berry will play that astronaut, Molly Watts.

“Extant is a very original concept with layers of humanity, mystery and surprise that reveal itself throughout the script,” said CBS Entertainment president Nina Tassler when they announced the series last year. “Our partnership with Amblin for Under the Dome showed that viewers respond to high-quality event programming in the summer. We look forward to building on that with Extant and offering CBS audiences another high-concept, unique event for summer television.”

This will be Halle Berry’s first series regular role in about 25 years.

“We received very positive feedback from Prime members about this summer’s exclusive access to Under the Dome,” said Brad Beale, Director of Content Acquisition for Digital Video at Amazon. “Customers loved being able to watch the show just days after it aired as well as catching up on previous episodes. We are thrilled to offer Prime members this access for Extant, another exciting new show from CBS.”
