When young Arthur's (Charlie Hunnam) father is murdered, his uncle Vortigern (Jude Law) seizes the crown for himself and tosses the boy out onto the streets. Robbed of his birthright and identity, Arthur runs the back alleys of the city with his gang, unaware of the life he was born for until he grasps hold of the sword Excalibur — and with it, his future.
Instantly challenged by the power of Excalibur, Arthur is forced to make some hard choices. Throwing in with the Resistance and a mysterious young woman named Guinevere, he must learn to master the sword, face down his demons and unite the people to defeat his uncle, finally taking his rightful place as King.
The crew members of the spaceship Covenant travel to a remote planet on the far side of the galaxy on a colonization mission. All of the members are couples, who are risking everything to form a new colony on the planet.
Once landed, they discover what seems to be a paradise, with fields of wheat. But when team leader Daniels (Katherine Waterston) notices the extreme silence of the planet, it's unnerving. There are no birds or animals — in fact, there are no signs of life at all. They discover evidence of an earlier doomed expedition. It soon becomes clear that there is something incredibly dangerous to human life on this otherwise beautiful planet.
