Moonshine Meat Market Mayhem (2016)

The film takes place in the not so distant future where the water is no longer drinkable and doing so would result in immediate death. Those that are punished to still be alive are riddled with cancer and rely on chemotherapy and moonshine to live. Those that can not find either soon perish and brought back as one of the undead known as cancer dancers. Surviving is brutal but so is death.
