We are a month away from the season premiere of HBO’s Westworld, and the network delivers the full-length, official trailer.

Set to a cover of Nirvana‚Äôs “Heart-Shaped Box”, the series finds the characters going against those who control the futuristic park, where robotic “hosts” look after the rich visitors who live out their fantasies.

We also get small glimpses of what lies beyond Westworld, as well as Dolores and the Man in Black, who attempt to break free of the fantasy world and begin a robot revolution.

Westworld season 2 premieres on April 22.
