You're an 18-year-old girl named Chloe Winters. Your parents have just left to go on holiday together, leaving you alone for the summer. Out of nowhere, your old friend JJ - better known to his fans as KSIOlajideBT - turns up at your door. After catching up, he invites you to stay with his group of friends known as the Sidemen. You get six new best friends and it's starting to look like the best summer of your life. But after a while, things begin to change. Drama and chaos happens. And you start to feel differently. Maybe you don't want to be just friends. Maybe you've fallen in love.
