In addition to heavy metal music musician Ozzy Osbourne, the show features his wife and manager Sharon, and their children Jack and Kelly. The Osbournes have another daughter, Aimee, who refused to participate in the show and publicly criticized her parents for their antics on the show. In most family photos shown on the show, she is either absent or blurred. The series also followed the family as they dealt with major events such as Sharon's battle with cancer and the aftermath of an ATV accident that nearly killed Ozzy.
