Mamma Mia! is a fun musical about a girl named Sophie who lives on a small Greek island with her mom, Donna. Sophie is getting married and wants her father to walk her down the aisle — but she doesn’t know who he is!

She finds her mom’s old diary and learns that there are three men who might be her dad: Sam, Bill, and Harry. Without telling her mom, she invites all three to her wedding, hoping to figure out which one is her real father.

When the men arrive, Donna is very surprised and confused. Sophie tries to keep everything a secret, but things get complicated! In the end, Sophie learns that family is not just about knowing who your father is — it’s about love and the people who care for you.
