The official teaser trailer for Alien: Covenant begins as blood marks can be seen on the floor of a spaceship's corridor and an overhead light flickers. An unsettling pounding can be heard, and soon enough, the sound is revealed to be a woman's (Carmen Ejogo) banging on a door. She is locked in a room with a man who is convulsing. She demands that another woman (Amy Seimetz), who's on the other side of the door, let her out. However, her request is denied and as she turns to face the man, a creature bursts out of his back.
The trailer continues as we're introduced to characters played by Michael Fassbender, Katherine Waterston and Billy Crudup. We see them, and their fellow space travelers, land on a planet and explore their newfound surroundings. But the action intensifies when they come across aliens. The creatures begin terrorizing the crew members, an explosion occurs, screams are let out and a steamy shower scene featuring a man and a woman gets gruesomely interrupted by one of the aliens.
