When someone tries to shoot the band 5 seconds of summer in their American tour, the government knows they have to take those guys to safety and hide them until they find out who tried to kill them. That's why the officer Moore offers his house as a safe place to protect them. The problem? his daughters. Anabelle Moore is happy to be out of school after probably the worst year anyone could have. She is ready to go to Cancun with her sister Abbigail, and to rest before college. But she can't do any of that because they all have to be locked up with the band 5 seconds of summer for them to be safe. It wouldn't be so bad if Annabelle's little sisters, Lily, Lola and Samantha weren't fangirling all the time just because their favorite band is living with them for the summer. There's also the fact that Calum and Abbigail can't stop fighting with each other. But then, when Ashton kisses Annabelle while playing hide and seek, she finally understands that her summer is way better than she expected, and she really wants to have more than just 5 seconds of summer if it means she'll keep those guys in that house forever.
