Milk

In a post-apocalyptic world, Lou, a goods trader (batteries, cloth, books, pornographic devices) stumbles upon a new business opportunity when he miraculously begins to lactate. Milk is a rare commodity in a world gone to hell, and so before long everyone in town wants a piece of the action, but there's something not quite right about the milk - other than the fact it came from a fifty year-old man.

¿The milk is bad, turning everyone that consumes it into radioactive mutants with a penchant for human flesh. Now it's up to Lou to put things right, before everyone he knows becomes a milk-guzzling cannibal.
Whatever you do, don't drink Lou's Milk...
