Clemens lives and breathes his grandfather’s stories. When his grandfather passes away, it is difficult for him to understand that it is now his turn to continue telling his stories. Story-telling becomes a way for him to not only keep the stories but also the memory of his grandfather alive.
Unfortunately the movie King Grandpa is not yet available on HBO Max.
