Unexpected

When the boys of One Direction were on x-factor 2010, they met a fellow guy and he happened to be Cassie and Claire's brother, Luke. Luke was quite talented and One Direction were afraid to lose to him so they decided to kill him. But of course no one suspected them. It was so unexpected, but is there a story behind it. 4 years later after lots of training Cassie and Claire want revenge. But when they kidnap the band what will happen?...
