Having solved the mystery of the missing dogs in Moscow, JR is ready for a vacation with his human, George, and George’s girlfriend, Nadya. And where better to distract themselves than in Prague, taking in the sights and meeting Nadya’s brother, a circus performer. But something is amiss at the circus—the animals are unhappy. The boxing kangaroo doesn’t want to box, the dancing chimpanzee doesn’t want to dance. Not only that, but a fancy new circus is coming to town, threatening to put everyone out of a job. It’s up to JR and his canine friends to save the show, with the help of some unlikely accomplices.
