Sophie seems to have everything going for her. She’s about to get married to the man she loves. She lives on a beautiful Greek island with a mother who cares about her. Her life should be perfect, but something is missing. Although she’s been raised by her loving mother, she’s never met her father. In MAMMA MIA!, Sophie longs to find out the truth about who she is; with three letters in the mailbox, she hopes to create what she’s never had: a traditional family. With the help of her mother and friends, she discovers that families come in many different shapes and sizes, and that love doesn’t always need to follow the rules.
