(CNN) Sacha Baron Cohen is starring in a new Showtime series that debuts this Sunday.

"Who Is America?" marks Cohen's return to television after more than a decade away. The half-hour satirical series has been in the works for over the past year, Showtime said in a press release on Monday.

The seven-episode series will "explore the diverse individuals, from the infamous to the unknown across the political and cultural spectrum, who populate our unique nation," Showtime said in its announcement.

"Sacha is a comedic genius who shocks you with his audacity, bravery and inventiveness," David Nevins, Showtime's CEO, said in a statement. "He is the premier provocateur of our time, but not for the sake of 'gotcha' moments. Behind the elaborate setup is a genuine quest for the truth about people, places and politics."

Cohen has been teasing the show for the past week on social media.
