I think the movie had some great humor within it but again this film had a lot of fighting. Strelka and Belka meet when Strelka's rocket riding circus act gets a little messed up and she gets launched into Belka's neighborhood. Belka has a friend who is a rat named Venya. The three get caught by a man and put aboard a train bound for the Soviet Space training Program. I enjoyed the teamwork and hard-work that the dogs display within the movie. This is a Russian film and it portrays the Sputnik space program with pride!
