I just saw this movie and can't remember the name of it.
Plot:
4 guys take off from their 9-5's and take a weekend trip into the desert in search of a party. One guy reveals he has mescaline to help them clear their minds and find their true path in life.
The party's over the next morning, and they find their truck's battery has been stolen along with some other things. They try to bargain with the thieves, and things go badly - really bad.
I can give more of the plot but some might want to see it for the first time. Reps to anyone who can help!
