Red Krokodil (2012)

Eating away at the soft flesh until it reaches the bone, the infamous Red Krokodil--Russia's highly impure and extremely toxic self-made synthetic drug--leads to an agonising death, before a repulsive scaly condition transforms the doomed user's epidermis into something that resembles a crocodile. Against the backdrop of ominous pre-apocalyptic signs, a slowly-decaying man who is addicted to the lethal flesh-eating drug cooks up fresh batches of the deadly concoction, trying desperately to escape from a horrible realm of despair, self-pity, and disturbing hallucinations. Is the poisonous substance the drug-addled man's only means of salvation? Will the corrosive Red Crocodile grant the man's wish?
