Starring Game of Thrones legend Lena Headey alongside Stephan James, it follows two people whose fates become entangled after they become trapped in outer space.

Headey's character Aster brings them to a mysterious lighthouse, but James's character Halan must figure out her real motives and whether she's friend or foe.

There are currently two seasons of the show out, but it can be a little tricky to watch them in the UK. That's where we come in!
