On this Saturday night, the whole town of Gerbier is gathered in the village hall to celebrate the work of Bernard Lepique, a local agro-food magnate and inventor of the famous «Almost Chicken», a 50% industrial, but, above all, 50% organic product. But when Bernard asks the people to taste his new product, the «Almost Braised», things begin to degenerate and the different Gerbelins (Gerbier inhabitants) present in the room are transformed into hybrid beings, half-zombie, half chicken creatures. Tracked by these strange creatures, our poor magnate must run away to save his skin.
