Thomas "Tom" Popper Jr. (Jim Carrey) is a divorced realtor whose father traveled to many far places around the world during his childhood. When his father dies, a crate containing a gentoo penguin (Captain) shows up at his doorstep. Eventually, due to a miscommunication, more penguins arrive (Bitey, Stinky, Lovey, Nimrod, and Loudey), bringing the total to six. Popper initially intends to donate the penguins to a local zoo, but changes his mind when his children, Janie Popper (Madeline Carroll) and Billy Popper (Maxwell Perry Cotton), fall in love with the birds.
At the same time, Popper is given the task of buying Tavern on the Green, an old restaurant that he used to eat at with his father as a child, with the intent of tearing it down and building a new development in its place. However, its elderly owner, Selma Van Gundy (Angela Lansbury), will only sell it to someone who she deems a person of true value. Having the penguins around helps Popper to become closer to his children and he begins dating their mother, Amanda Popper (Carla Gugino), again. The penguins eventually lay three eggs. Two of the eggs hatched and one doesn’t. Popper becomes obsessed with saving the last egg, losing his job in the process.
