Undercover Agent Malcolm Turner is back and this time he's out to expose the suspected designer of a deadly computer "worm" that would allow outside forces access to sophistical and critical government intelligence files. But unfortunately, the only way the crafty agent can get next to the worm's creator, Tom Fuller, is to access the programmer's Orange County home as the new "nanny" to Fuller and his wife Leah's children: toddler Andrew and his two older sisters, Carrie and Molly. This means that Malcolm must once again rely on his sure-fire alter ego, the take-no-prisoners Hattie Mae Pierce, a.k.a. "Big Momma," to bring down the bad guys and prove that a woman's work is never done! But once undercover, the job proves another tough juggling act for Big Momma as "she" must manage the hectic lives of the three Fuller kids, keep up with their myriad of daily activities, and handle the many household chores, all while secretly trying to dig up information on Tom's computer virus. Of course, Malcolm's hardest and most comical task is staying in Big Momma character throughout, which requires the trickiest of physical and vocal transformations, not to mention the ability to think really fast on his pumps. Hilarious situations ensue for "Big Momma" while trying to trap her prey, including, infiltrating a ritzy women's day spa, leading a bawdy teen cheerleading competition, and surviving a crazy jet ski chase, all while trying to keep "her" wig straight and skirts smooth. Along the way, "Big Momma" also helps bring the fractured Fuller clan back together and, in turn, Malcolm develops a newfound appreciation for his own family, which includes stepson Trent and expectant pregnant wife Sherrie. Malcolm also learns he can strike a successful balance between his work and home responsibilities, without shortchanging either side in the process.
还行，不过叙事比第一部散了很多
还是很搞笑的 但是第一部经典一点
哈哈哈哈哈哈 真的 为什么结尾还要重放一遍沙滩！！
感觉比1好看，从喜剧效果来说

不亚于1的继作
不是保姆 这是保镖！
比起1、3剧情弱了点，合家欢电影
感化+拯救，同时不忘主线剧情，模式应该固定了吧
补
