- 55 year old Bernd is looking forward to a quiet weekend at the lake with his best friend Klaus and his brother Peter. Everything could be so perfect, but Murat is also joining them - a young Casanova, who just recently broke the heart of Klaus' daughter. And Klaus doesn't want to miss the opportunity to teach him a lesson about how to respect woman. A well intended mission suddenly turns shaky. When Klaus wakes up the morning after a rough hit on his head, he suddenly wants to walk his dog Rudy. Though unfortunately Rudy passed away 2 years ago. The men are faced with a difficult decision: Should they tell their friend that Rudi is dead and risk breaking Klaus' heart again? ... but good friends are there to always help each other, so they all head to look for the dog that allegedly has gone missing.
