All Your Love on Me"). At Sophie's hen party, Donna and the Dynamos don their old costumes and perform a song ("Super Trouper"). Sam, Bill, and Harry accidentally walk in on the party, and the guests persuade them to stay ("Gimme! Gimme! Gimme! (A Man After Midnight)"). Sophie first pulls Sam out of the room to talk to him. After he asks why he is there, she is overcome with guilt and goes to talk to Harry, instead. Harry asks if Sophie's father is at the party, and she tells him the whole truth. Lastly, she draws Bill aside to talk with him. She learns that Bill has an aunt Sophia who left all her money to Donna's family.

Then, Harry approaches Sophie, apologizing for being so slow on the uptake; he is also convinced that she is his daughter and promises to walk her down the aisle. Sophie leaves the party, hopelessly confused; she doesn't want to turn any of them down ("Voulez-Vous"). Act II (Entr'acte) Sophie's having a nightmare, involving her three possible fathers all fighting for the right to walk her down the aisle and wakes up despairing ("Under Attack"). Sophie's upset, and Donna assumes that Sophie wants to cancel the wedding and offers to handle all the details. Sophie's offended and vows that her children won't grow up not knowing who their father is. As Sophie storms out of the room, Sam enters and tries to tell Donna that Sophie may not be all she seems, but
