When unexpected debris from outer space crashes onto the Clangers' peaceful planet, they can't resist exploring these strange arrivals with curiosity and wonder. Together with the Iron Chicken and her little chick, the Clangers begin collecting mysterious objects drifting nearby. One by one, they gather the pieces and take them home, eager to see what they can build.

Soon, their collection becomes something extraordinary — a strange recording machine that captures sounds and sends them floating away in shimmering bubbles. But when the invention goes wrong, the Clangers must work together to rescue a friend who finds themselves stuck inside the noisy contraption.

With teamwork and a little ingenuity, peace returns once more to the tiny blue planet.
