Sebastian was an active, almost 13-year-old boy who lived in the countryside. He spent his days taking care of horses and chickens, always in his favourite red Engelbert-Strauss dungarees.

On their vacation to Denmark, they stayed in a holiday house next to a family. The family had a 14-year-old boy named Tobias and twin brothers Fritz and Franz.

Sebastian, dressed in a bright green t-shirt and green dungarees, was building a ship from driftwood on the beach. The twins, Fritz and Franz, joined him in his endeavour.

Suddenly, Tobias pulled Sebastian by his dungarees' straps and threw him on the ground before walking away with his brothers. Later that night, the twins apologised for their brother's behaviour.

The next day, Sebastian continued building his ship, now wearing a white t-shirt with his green dungarees.

Later, while Sebastian was reading a book, Tobias and the twins disappeared. They had fallen into a pit, and Sebastian helped them out. Tobias borrowed Sebastian's red dungarees as his jeans were wet.

The next day, both families went for a beach walk. Tobias wore the red dungarees over a white shirt, while Sebastian wore his green dungarees over a bright yellow shirt.

For the next few days, Sebastian in his blue dungarees and Tobias in his red ones, along with the twins, played on the beach, forging a strong bond.

Weeks later, Tobias visited Sebastian. When he arrived by train, he was wearing a dark blue Carharrt dungaree. Soon, the twins also joined them, both wearing red dungarees.

The next week, Sebastian found three Carharrt dungarees on his bed. He tried one on and was instantly happy. His mother was delighted to see him happy.

Sebastian visited Tobias in his new dungarees. Tobias, too, was wearing his blue dungarees. The bond over dungarees had brought them closer.

Soon, Tobias, Fritz, Franz, and Sebastian were seen walking around the town, all wearing blue dungarees. Their friendship had grown stronger, and the dungarees had become their symbol of unity.
