Pig Hunt (2008)

John and his friends plan on going away for a boys only hunting weekend.  But John's girlfriend decides to tag along and John isn't able to tell her no, much to the displeasure of the others.

John's deceased Uncle's cabin has been vacant since he died.  The cabin is deep in the woods and in order to get there, they have to drive by a house full of creepy hillbillys, who we later find out are related to John.  Cousins Ricky and Jake come by the cabin to talk to John and tell him about a 3000 pound pig they call The Ripper.  A giant pig?  Who wouldn't want to hunt a pig bigger than a car?

The two hillbillys also offer to guide John and his friends through the woods. Other than John, who is a veteran, the other guys don't know how to shoot, so it's probably not going to be the most successful hunting trip.  Several of them are more interested in the fields of pot they find growing in the middle of nowhere.

When John and his cousin get in a fight, one of John's friends goes to far to protect him, resulting in the whole hillbilly clan going crazy and out for revenge.

You'll keep forgetting that there are also hippies in the film. Every once in awhile they show up briefly, but then they slip your mind.
