Benjamin Mee is still grieving the loss of his wife Katherine and dealing with the expulsion of his 14-year-old son, Dylan, from school, and decides to make a fresh start by buying a new house. He tours many houses with his 7-year-old daughter, Rosie, and his realtor, Mr. Stevens, but finds none he likes until his daughter finds a listing with what seems like the perfect house. They drive to an old large house and Benjamin inspects the property, telling his realtor it is perfect. When they hear a lion roar, Stevens explains that the house comes with a zoo in the back, which closed several years before; if they want the house, they must buy the zoo.
