Animal pals Alex, Marty, Melman, and Gloria are still trying to make it back to New York's Central Park Zoo. They are forced to take a detour to Europe to find the penguins and chimps who broke the bank at a Monte Carlo casino. When French animal-control officer Capitaine Chantel DuBois picks up their scent, Alex and company are forced to hide out in a traveling circus.

Alex, Marty, and other zoo animals find a way to escape from Madagascar when the penguins reassemble a wrecked airplane. The precariously repaired craft stays airborne just long enough to make it to the African continent. There the New Yorkers encounter members of their own species for the first time. Africa proves to be a wild place, but Alex and company wonder if it is better than their Central Park home.

An abortion clinic worker with a special heritage is called upon to save the existence of humanity from being negated by two renegade angels trying to exploit a loophole and reenter Heaven.

一转眼，伍迪艾伦（Woody Allen）这个老头已经陪伴我们度过了数十个年头，从黑发到白发，从壮年到老年，我们作为观众，几乎可以说是在电影里目睹了伍迪艾伦的整个后半生。从最初的无厘头喜剧《傻瓜入狱记》到最新的爱情小品《爱在罗马》，伍迪艾伦在电影中完成了对人生和爱情的讨论和探究。
在自己的电影中，伍迪艾伦扮演过无数个让人啼笑皆非的角色，然而，在现实中，他究竟是个怎样的人，我们无从而知。同时，不时传出的花边新闻也让这个在影片里絮絮叨叨的男人的身影愈加的模糊起来。影片采访了这些年来和伍迪艾伦合作过的演员和导演们，通过他们的语言拼凑出了一个陌生但真实的伍迪艾伦。
