Madagascar 3: Europe's Most Wanted

In their quest to make it back to the New York zoo from whence they came, Alex, Gloria, Marty and Melman have ended up in Monte Carlo. After an incident at a casino, they find themselves on the run from Capitaine Chantal DuBois, a vicious and unrelenting animal control agent. To escape her clutches, the gang stow away on a circus train and end up joining the ailing travelling show to help revitalise it. They even make some new friends along the way.
