I can’t remember the  name of this movie. This guy is trying to catch this other guy for hanving these events a few times a year, where they would eat exotic animals but feed them turkey. I remember the ending. The guy finally catches the guy and they are in the kitchen, the event is in a tent in a cornfield where only they very rich can get in. The man learns that it is all a scam. Thy import these exotic animals and show them off to the consumer but just give them turkey later on because the supposed gangster is actually a nice guy. It was in English and probably ,add in the 70s or 80s
