Duffy Kerrigan has three adopted siblings. Seth from Nigeria, Juan from Mexico, and Pearl from Hong Kong. One of their first trips with their father is to Africa. There Duffy immediately becomes critical of the different way Africans do things. As she learns more about the culture, she discovers that different does not necessarily mean wrong and that much can be learned from other cultures.
Traveling with their father to England, the Kerrigan Kids quickly learn the differences between life in America and England, such as cars driving on the 'wrong' side of the road. While the rest of the family is having fun leaning new things, Juan is overcome by a complaining and selfish spirit. However, the lessons he learns about English culture serve to teach Juan the importance of putting others needs ahead of his own.
The Kerrigans learn valuable lessons as everything begins to go wrong on their trip to Australia. Their luggage was misdirected, the girls suffer food poisoning, Mr. Kerrigan loses a contact, and their all-purpose vehicle breaks down on a rural road. The Kerrigans learn the valuable lesson that bad things can happen to good people and that it is critical to trust in God even during difficult circumstances.
Pearl gets the opportunity to visit the area where she was born when Mr. Kerrigan is assigned a job in Hong Kong. On the plane, the family meets two young children who are going to live with their Grandparents in Hong Kong. However, there is no one to meet their new friends at the airport so the Kerrigan clan puts into practice what they recently learned about the Good Samaritan. As they make sure the children find their grandparents' house, they make new friends, and learn about Chinese culture.
