Lea, Steffi, Toni & Maja have vowed to celebrate each others weddings together — 26 years ago, things you do at twelve. Now Maja spontaneously invites the others to Italy. A promise is a promise! The trip begins moderately and gets worse and worse. It confronts them with missed opportunities, loss and their long lasting friendship.
