Mamma Mia! (2008) on Netflix

Many people are descending on the Greek island of Kalokairi, specifically to the rustic resort hotel called the Villa Donna, owned and operated by single mother Donna Sheridan, for the wedding of Donna's twenty year old daughter Sophie to her boyfriend Sky. Three of the people who are coming to the wedding but that Donna doesn't know are coming are architect Sam Carmichael, banker Harry Bright and sailor Bill Andersson, none of who Donna has seen in over twenty years. Unknown to her, Sophie invited the three since she, who gleaned as much from secretly reading Donna's diary, knows that the three were men involved in her mother's life when she was conceived and thus surmises that one of them must be her father. She wants that man to walk her down the aisle and give her away. With help from her bridesmaids Lisa and Ali, Sophie tries to figure out which is her father. When Donna sees the three men, she, with the help of her best friends and former singing partners Rosie Mulligan and Tanya Wilkinson, also tries to figure out what she will do with these three. Meanwhile, the men, who didn't know each other or of each other before arriving on the island, quickly surmise the reason why they were invited, each believing he is indeed Sophie's father. As complications ensue from the misunderstandings, Sophie and Sky's wedding and relationship may be jeopardized, while, finding what is truly in their hearts, many may discover the course of true love.
