The four friends and self-proclaimed "muscle animals" Lea (Jessica Schwarz), Steffi (Julia Becker), Toni (Petra Schmidt-Schaller) and Maja (Nora Tschirner) swore as children that they would definitely celebrate their weddings together. 26 years later, Maja demands at short notice via video message what was solemnly sealed between gymnastics club training and an overnight party. Pinching doesn't count! For Lea, Toni and Steffi, the trip through sunny Italy starts moderately well, because they have an unexpectedly long drive to Maja's wedding location ahead of them. An undersized rental car is just the beginning of a chaotic road trip that will see the disparate 30-somethings reconnect with missed opportunities, painful truths, and the core of their long-standing friendship.
