The long-awaited day has arrived for Rabbit Charlie - he's finally turning five. However, the grand birthday celebration is uncertain. Will the party go as planned?
Meeting with friends, fishing with dad, and eating carrot cake - that's what Rabbit Charlie had planned for his big day. After all, fifth birthdays only come once in a lifetime! But ever since his younger sister was born, his parents haven't been paying him as much attention as they used to. When unexpected events lead his mom and dad to leave, he decides to celebrate the occasion in his own way.
An adventure ensues as he embarks on a journey alongside his friend Monika and her cheerfully wagging dog. In the forest, they encounter frogs, snails, and a fox with not-so-good intentions. During the expedition, Charlie will come to understand the true meaning of friends and family. These will be an unforgettable birthday!
The film is based on the bestselling book series Karlchen (Little Charlie) by Rotraut Susanne Berner, one of the most popular children's book illustrators in Germany.
