Taking place on a fictional Greek island, the show uses ABBA’s greatest hits to tell the story of a young woman on a quest to find her real father. Sophie Sheridan is about to be married and desperately wants her father to give her away. Since her mother refuses to talk about the past, Sophie reads her mother’s diary and finds the contact information of three men that she had intimate encounters with. She invites each of the men to her wedding and they all come. Eventually, however, it is clear that Sophie’s paternity is undetermined. But everyone involved agrees that they want to be a part of Sophie’s life.
