What is this flick's general gist? 
I just watched the whole thing. Retired porn star gets an offer for lots of cash for a new movie, but they won't tell him what he's filming. Things turn bad for him. At one point he's violently corn holing his 5 year old son while his brother fucks his wife.
One part that needs to be mentioned is the "newborn porn", dude delivers a baby, slaps its ass and then fucks it.
I'd say it's a pretty good movie, as long as you don't jerk off while watching it. If you do get hard and jerk off during this movie you should probably kill yourself.
