Davis' carefree existence is turned upside down when his orphaned nieces and nephew land on his doorstep. Davis becomes an instant father figure to six year-old twins, Buffy and Jody and their big sister, Cissy. Through humorous trial and error, coupled with big doses of love and patience, the five become a real family.
