I am a movie director and I just received the following movie plot. Could you help me answer this question? If not, let me know by writing "Not answerable". Plot title: Madagascar 3: Europe's Most Wanted Movie plot: Many days after bidding the penguins goodbye, Alex suggests to his friends and the lemurs that they should go to Monte Carlo to get the penguins and the chimpanzees and fly back to New York City, which they agree to do. In Monte Carlo, the penguins and chimpanzees have been saving up their daily winnings from the casino to fly back to Africa and bring their friends home. Alex's interference to kidnap them leads to animal control, led by a vicious big-game hunter named Chantel DuBois, pursuing them around the city, with Alex and the gang barely escaping. With determination, DuBois vows to capture Alex and add him to her collection of animals she's captured (through taxidermy). In the skies of France, the plane crashes as the authorities close in. They come across a circus train consisting of Stefano, Gia, and Vitaly, and manage to gain entry, claiming that they are circus animals themselves. The animals soon learn from Stefano that they are performing in Rome and London, where they plan to impress a promoter to get them on their first American tour. Before the zoo animals' claim is discredited, the penguins suddenly appear with a deal to purchase the circus themselves; however, the circus animals' show in Rome proves to be a failure. In route to London, Stefano soon reveals to Alex that Vitaly was the biggest star of them all, but quit due to an accident in one of his stunts; therefore, the friends losing faith in the circus. At a stop in the Alps, Alex convinces the circus to continue pursuing the circus, in the process they grow closer. Meanwhile, DuBois is arrested in Rome while chasing the animals, but escapes and discovers that Alex was the missing lion from the zoo in New York. Once free, DuBois recruits her injured men and they head toward the Alps, forcing the animals to proceed to London despite incomplete rehearsals. Alex finds Vitaly preparing to leave and convinces him to stay by reminding him of how he enjoys performing the impossible. He suggests that he uses hair conditioner as a safer lubricant... My question: Whom is animal control led by?
