It shows Dolores (Evan Rachel Wood) plotting some form of rebellion as she and the other hosts who escaped Westworld - including the new version of Charlotte Hale (Tessa Thompson) – are hunted by humans.
It seems she’ll be helped by Aaron Paul’s new character who can be seen cradling an injured Dolores in his arms at one stage.
Meanwhile, Maeve Millay (Thandie Newton) finds herself in a brand new park – set during World War II.
Other stars featured in the trailer include returning cast members Jeffrey Wright and Luke Hemsworth alongside newcomer Vincent Cassel.
Westworld returns to HBO in 2020.
