Set before the original Alien film, Alien: Earth follows a team of researchers from Earth set out to learn what’s hiding on a space ship that happens to crash land onto their planet one day. As a person whose mind has been transferred into a durable, synthetic body, Wendy (Sydney Chandler) is an ideal candidate to investigate the downed ship. It’s not clear to anyone where the vessel might have come from or why it crashed, but CEO Boy Kavalier (Samuel Blenkin) knows that he wants whatever is on it.

As Wendy, her fully-synthetic mentor Kirsh (Timothy Olyphant), and the rest of their team board the ship in the trailer, it’s immediately clear to them that, at one point, it was being used to transport dangerous creatures. And while all of the bloody, broken containment units tell a pretty clear story about what went wrong, it takes Alien: Earth’s characters a few beats to realize how much of a deathtrap they’ve wandered into.

Though the trailer’s actually pretty light on shots of the aliens, it gives you a pretty good sense of how solid the show’s production design is going to be. It also lets you know that these creatures are going to give the humans hell, but we won’t know how the story unfolds until the series premieres on August 12th.
