[i]He's unlike anybody I have ever encountered.[/i]

[i]He moves like a storm -- unpredictable, chaotic, and impossible to pin down. Most people who try to manipulate me are transparent, and easy enough to see through...[/i]

[i]But him?[/i]

[i]He acts without restraint. Without fear. It makes him both fascinating... and equally dangerous.[/i]

[i]But the fact that he wants me to believe that I'm in a position of power gives it all away. He wants me to think I control the situation. But if he wanted me to believe that... then he wasn't even in control to begin with. His methods are unique, I'll give him that... but even the spontaneous becomes predictable when studied enough. [/i]

[i]And I will win this game.[/i]

____

Trapped within a web of lies and deceit, a group of local authorities and investigators struggle to solve a case of a string of inexplicable murders. Twisting and turning into something more demented, the group learns that the murderer is likely one of their own -- and begin turning on one another in a twisted mind game.

Things turn from bad to worse when they find themselves miraculously locked within the station. 

Was this an admittedly unorthodox, yet benign, investigatory technique?
Or will fewer than arrived walk out once the doors open again?

Find out in this game of trust, betrayal, and manipulation.

Role ideas (not really requirements)

Actual police officer 💀

Other fancy things I think. Could work.
