You are an officer in internal affairs. Your job is to the catch cops who strayed off the righteous path.
You are good at your job. You are proud of your job.
There is a small problem however. You see, you may have skeletons in your closet too. Maybe you are aware of them. Maybe you forgot them. And maybe someone remembers them for you.
In this card game you take the roll of a cop trying to help fellow cops hide evidence against them before the "good cop" arrests everyone, all while trying to figure out if you are the "good cop" yourself.
