It was supposed to be the best night of the year. Senior lock-in. No teachers. Pizza. Games. Stupid confessions and hallway races in socks.

But it all changed when the lights flickered and stayed off.

Every phone? No signal. Front doors? Locked. The PA system cracked to life.

"Let’s see what the Class of 20XX is really made of." "Level 1: Chemistry Lab. Five minutes. Or else."

Everyone laughed—at first. Until the fire alarm blasted. The sprinklers went off. And the science room literally locked shut behind the first five people who entered.

The screams that came after? Real.

Now the school’s become a twisted maze. Every “level” is a challenge: trust, fear, betrayal.

But the real kicker?

Someone in your class is controlling it.
