William Collins (Aaron Taylor-Johnson) is a depressed teenager recovering from self-harm and regularly goes online to chatrooms. One day, he decides to open a chatroom himself and calls it "Chelsea Teens!" and where he meets Jim (Matthew Beard (British actor)), another kid; Eva (Imogen Poots), a model; Emily (Hannah Murray), a goody two-shoes; and Mo (Daniel Kaluuya), a normal kid. There is no real subject matter in "Chelsea Teens!" which instead focuses on the lives of each teen as they talk. Even though they only really communicate through text, the film depicts them in an old hotel-like room and actually having contact.
