The story takes place on a mythical Greek island in the present day, and centers around a young girl named
Sophie who dreams of a white wedding, with her father giving her away at the altar (I HAVE A DREAM).
Problem is, she doesn't know who her dad is - and she's getting married the next day. As the show begins, she explains to
her chums that her mum, Donna, fell into the arms of three men within a short space of time. So she's got three possible dads,
and has invited them all to the wedding (HONEY, HONEY).
mum, a tavern hostess, used to front a rock chick band called "Donna and the Dynamos." Her former bandmates - the tomboyish
Rosie and the glamorous Tanya - show up for the wedding, and talk over how life has turned out for them (MONEY,
MONEY, MONEY). They're not the only ones who turn up though - so do the three possible dads, whom Sophie convinces
not to tell Donna that she invited them (THANK YOU FOR THE MUSIC). Donna is surprised, to say the
least, at the sight of the new arrivals (MAMMA MIA).
Convinced that this new twist will
ruin everything, she escapes to her room, where Rosie and Tanya do their best to cheer her up (CHIQUITITA).
They discover momentos of their old rock band days, and try to see if they've still got it (DANCING QUEEN).
Sophie is not much happier - she'd been sure she'd be able to tell at first sight which one was her father, but she has no
clue. Sky (her fiance) tries to cheer her up, while his friends try to steal him away for the traditional bachelor party,
beginning with a deep-sea dive (LAY ALL YOUR LOVE ON ME).
At Sophie's own party, Donna,
Rosie and Tanya make their triumphant return to the stage (SUPER TROUPER). The three "dad"s, Sam,
Bill and Harry, are also present, and as the only men there are subjected to the attention of the girls (GIMME!
GIMME! GIMME!). Sophie talks to each of the men, and all of them become convinced that the reason he has been invited
is because he is Sophie's father (THE NAME OF THE GAME). Sophie returns hopelessly confused, while
the party carries on (VOULEZ-VOUS).
The second act begins with Sophie's nightmare about
her wedding, where there are three men fighting to give away the bride, who isn't what she seems (UNDER
ATTACK). Sam is the first to try to speak to Donna about his suspicions, but all she can think of is the past (ONE OF US). It turns out Sam, who may have been the love of her life, left her. They both wish they
could go back to the time when they were open with one another (S.O.S.).
has been fighting off advances from one of the boys that works for Donna, and finally manages to put him down once and for
all (DOES YOUR MOTHER KNOW?). Sam tells Sophie something about his failed marriage, trying to ensure
she knows what she's getting into with Sky (KNOWING ME, KNOWING YOU). Harry has also decided to
speak to Donna, and they begin to reminisce about the time they spent together (OUR LAST SUMMER).
Sophie herself arrives and Donna helps her finish getting ready for the wedding, hardly able to believe her little girl is
getting married (SLIPPING THROUGH MY FINGERS). Sam returns again, emboldened by his talk with Sophie,
but Donna still doesn't want to have anything to do with him, and asks him to leave (THE WINNER TAKES
An attraction has been growing between Rosie and Bill, who find themselves alone in the church before
the wedding. She decides to take matters into her own hands (TAKE A CHANCE ON ME). The wedding
begins, with Donna giving the bride away. However, Sophie's been doing some thinking, and puts an end to the proceedings,
saying she's just not ready. But someone else is - Sam explains his desertion of 20 years ago and asks Donna to marry him.
Shocked, but happy, she agrees (I DO, I DO, I DO). Content with having three dads rather than just
one, Sophie leaves with Sky to find their future (I HAVE A DREAM).
