Sailor Jennings, better known as "The Captain" is guilted into being manager/mom of the four hooligans who make up the band "Part Time" by her long time best friend Louis Tomlinson. When the drummer decides to split due to personal reasons, they're scrambling to find a new one. Harry Styles is a loner who moved to London in hopes to promote his music and get a jump start on his career so when he notices auditions for a drummer in a band, he jumps at the opportunity. Low and behold, he's the perfect fit for "Part Time" and soon four hooligans become five. Everything seems to be working out for everyone...until feelings are brought to the surface and secrets unfold. And the biggest question of all... What happened to Sailor last summer?
