Sarah loves to spend her time reading romance books and dreams of living a love story like the one in her books. She never thought that a forgotten rucksack in the park would give her just that. Without further ado, Sarah sends the rucksack back to its owner, along with a letter. When Chris accompanies his best friend to the U.S. Army recruiting office and then forgets his backpack in the park, he never imagined that this backpack would become his wingman. A week later, his backpack arrives back at his house - along with a letter. They get to know and love each other only through letters, without ever having seen each other. And it all started with a forgotten rucksack.
