Is this a school?

[This my first try at making an AI story. Be kind, please.] You play a student that got enrolled in a mystery place of education. It all seems normal, but when you open the 'school's' front door, the building innards are not school-like. Not at all. The doors close & trap you inside. 3 other students are lost elsewhere, they seemingly fell into the same trap. Is this really a school? Can you escape? Can you trust your fellow 'students'?
