After a successful operation in the U.S., Zuzia returns to Poland with her parents. During her absence, her beloved dog—Lampo, known by many as ‘PKPies’—is entrusted to the care of the railway station director.
At first, life seems to settle down, but chaos soon ensues: Lampo still loves traveling by train, leading to funny mischief and unexpected situations. One day, he doesn’t return as usual, and all traces of him disappear—the GPS on his collar is no help. The desperate station director tries to make up for it by taking in a dog of the same breed from a shelter to replace Lampo. When Zuzia returns to Poland, she realizes that the dog at the station, being adored by the public, is not her Lampo—it’s a female named Luna. Together with her friend Antek and their new furry companion, she embarks on an adventure to find the real Lampo.
