Eight-year-old Martyn and his dog Babaka always bring back finds of dubious value from their walks. A deflated ball or broken binoculars... But one day, Babaka comes across a strange place and starts bringing his owners incredible items: a stopwatch that slows down time, a pen that writes what a person does not dare to say.

Magic? No! It was a mail starship of the Intergalactic Delivery Service that crashed to the ground.

Martyn's family meets Luciano, a star courier who looks like a gawky pigeon. They take on an extremely difficult task: to help the alien return home. But people don't even suspect that they are about to face another challenge - no less than the salvation of the universe. Only a miracle can overcome the global trouble. Or erudition and ingenuity.
