Die Oma ist tot (1997)

Grandma Vera travels by bus from a small Polish town to Pinneberg to celebrate her birthday with granddaughter Linda, her husband Lothar and their two children Jan and Christina. Together with Lothar's stuffy, uptight parents, they spend a fun-filled evening. But the next morning, Grandma is dead. Although Grandma Vera actually wanted to lie next to Grandpa Pyotr in her hometown of Kovalov, the family cannot afford an expensive funeral. So there is only one option: to transport Grandma themselves.
