Scabrously witty, shockingly violent and at times positively hallucinogenic, The Aliens is a wry and lawless adventure. Since they crash-landed in the UK 40 years ago, aliens have lived among us. Though they look and behave exactly like us, they are forced to live a segregated life, behind a huge wall in a ghetto called Troy. It's a hedonistic and ramshackle town, unpoliced and filled with gangs who make a living smuggling alien hair out of Troy to be smoked as a drug by humans. Lewis (Michael Socha) is a border guard at the checkpoint that patrols the wall, but after a chance encounter with mysterious alien Lilyhot (Michaela Coel) his life is thrown into turmoil when he discovers that he's actually half alien.
