In M. Night Shyamalan's latest outing, everyone in a large city is in a frenzy. Why? That's because they're up and ready to watch a concert performed by famous pop star Lady Raven. Two of her fans, a man named Cooper and his daughter Riley, attend the concert with high spirits, but things slowly begin to change their tune. Amongst the screams of adoration and sounds of applause, the concert itself has a hidden identity: a front to fish out an infamous serial killer known as The Butcher. With security cameras rigged, armies of policemen with weapons at the ready, and police vehicles surrounding the venue, will anyone survive their concert experience or is there more to The Butcher than meets the eye?
