30 years have passed since Andreas, Nils and Thomas graduated from high school. When they receive an invitation for a class reunion, the three friends face a crisis as the big dreams and goals of their younger selves have long evaporated into thin air and have given way to the disillusionments of adulthood: relationship problems, rebellious children, stress at work. Still, they want to prove to themselves as well as to their former classmates that they still got it. Thus, the trio heads out early to spend some extra days at the luxury hotel where the class reunion is set to take place. They plan to let their hair down just like in the good old days. Unfortunately, Thomas brought a chaperon with him: Lili, the sassy daughter of his girlfriend Linda, who gave Lili the order to keep an watchful eye on the DJ and womanizer. When the day of the class reunion finally arrives, it doesn’t take long before chaos takes over.
