I made the mistake of being bored and watching a YA novel adaption called "Panic". (It's bad.) 

And to save you the time I wasted, here's the plot and I'll let YOU guess what the twist is.

There's a small town where (30 year old actors playing) teenagers run a super secret game that everyone in town knows about. Except the police. [s]Yes that already doesn't make any sense. But hear me out.[/s] And these "tradition of games" have lead to reported injury, death, and crime. Where dozens of teenagers are apparently stupid enough to kill themselves over 50 grand.

BUT, ya see, there's a twist. Someone is secretly behind a conspiracy to...what? [i]How did you guess that the bad guy was the cop?[/i] I haven't explained the rest of the plot yet and-
