A group of attractive young people (of course) awaken to find themselves prisoners in a mysterious house with no means of escape. They are each outfitted with new accouterments–electronic devices attached to the base of their skulls–and a recording on a television screen alerts them of their task. In order to escape, they must hurt themselves and each other. The chemicals that the brain produces when in pain are collected by the devices, and when it collects a predetermined amount, the doors will be opened. Fail to do it in time, and everybody dies.

Music fans know Maynard James Keenan as the frontman of such bands as Tool, A Perfect Circle, and Puscifer, but in this documentary filmmakers Christopher Pomerenke and Ryan Page offer a closer look at one of the prolific rocker’s more unexpected hobbies — winemaking. Along with his business partner Eric Glomski, Keenan has managed to transform an arid stretch of Arizona desert into a lush vineyard that yields some particularly tasty grapes. Through unguarded conversations with Keenan and Glomski, Pomerenke and Page discover just what got the pair interested in winemaking, and why they chose such a hostile natural environment to serve as the site of their winery.
