JR and his embassy friends Robert, Pie, and Beatrix are on their way to
Prague! Having solved the mystery of the missing dogs in Moscow, JR is
ready for a vacatio with his human, George, and George's Russian
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 the embassy
dogs to save the show, with the help of some unlikely accomplices.
