The film is based on an old fable about a chicken who yelled that the heavens fall to the ground every time an acorn fell on his head. For a year now, Chicken is trying to overcome the shame of his mistake (about falling heaven) and live as if nothing had happened. But - alas! - there are a few those wanting to be friends with a little looser, and therefore his comrades are the same rogue, like himself. But once a misfortune really happens - it's time to sound the alarm! But who will believe Chicken, because he already goofed once. Now the future of the planet depends on the humble soldier and: an accelerate piglet, a miserable duck, a mutant goldfish and Chicken, whom nobody wants to know.
