Rough neighbourhood, the sort of place where protection rackets are the norm. Local businesses get together and devise their own in-house protection racket. While it might appear to be the real deal, the gangsters are actually employed by the businesses. Cheaper than actual extortion, and protects the businesses as well.
The people they hire, let’s just say you can sometimes spot some flaws in their charade. Cosplay almost.
Real gangsters decide to take over the territory and the fake gangsters need to man up.
Basically a mafia version of Galaxy Quest.
