CJ Haugh has just arrived at her new school at Ireland. The five lads, especially Niall, have taken quite a liking to CJ and welcome her whole heartedly to their crew. Niall and CJ go through a bunch of obstacles and dillemma's with each other that bring them closer together as friends, and maybe even more than friends.

Teagan Sky is in for a rough year. Her mother is being transfered to Tokyo for a year and she can't take Teagan with her. Not that Teagan woud go anyways. At 17 years old, she's old enough to take care of herself, but not old enough to stay home alone for a year. Nobody is willing to take in Teagan for a whole year, especially if they know her well. Trouble and mischeif follow her eveyrwhere. But sure enough, her mother finds a spot for her, with an old high school friend who owes her a few favours. Her son is 18, living solo, certainly has room for Teagan. But this son isn't a regular 18 year guy. He sells out tours in 11 minutes, he makes albums and he has millions twitter followers. Why? Because this 'son' is Harry Styles and he and his four friends are about to make this year unforgettable.
