The songs of the pop group ABBA provide the score for this romantic comedy which contrasts the dreams and aspirations of a young woman about to become a bride with those of her mother, a free spirit of the 70s who never married. Mamma Mia! takes place at a taverna on a Greek island in the summer of 1999 over a 24-hour period.

Donna spent the summer of 1979 traveling after college and met Bill, Harry, and Sam. Her daughter Sophie was born in 1980 when Donna was about 23 years old. All are now reunited for Sophie’s wedding.
