WESTWORLD season four picks up over seven years later after the protracted war – humanity is finally free. Or so it seems. Maeve and Caleb soon begin to suspect that Hale and a host version of The Man in Black are seeding a conspiracy to regain control of the human race. Meanwhile, Bernard returns from The Sublime with a new power. And a young writer, by the name of Christina, begins to question the nature of her reality. With returning cast members including Evan Rachel Wood, Thandiwe Newton, Ed Harris, Jeffrey Wright, Tessa Thompson, and Aaron Paul, Westworld continues to thrill as it deftly weaves together stories about the complicated relationship between man and machine.
