"Extant" is a futuristic thriller that follows a female astronaut who tries to reconnect with her family when she returns after a year in outer space. Her experiences lead to events that ultimately change the course of human history.

"Extant is a very original concept with layers of humanity, mystery and surprise that reveal itself throughout the script", said Nina Tassler, President of CBS Entertainment. "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".
