Zorro is one of those dogs who are trained from early childhood to be bloodhounds. He is obedient, quiet, extremely attentive - and most importantly, he can smell a person even in a deep forest. Or under thick snow. For Zorro, saving those in trouble is not only work, but also pleasure. And the first person to express gratitude to the dog was Luka, a 19-year-old snowboarder who was covered in an avalanche one ill-fated day. Luka is not only grateful to Zorro - looking at his daily exploits, the guy decides to change his life and become a professional Alpine Aid volunteer. And for this he needs his own four-legged companion. Puppy Pappy from the dog shelter can become it. There, at the shelter, Luka meets an amazing girl, Marie, but it is so difficult to find a common language with her! And only Zorro helps to do this. The stories of Zorro, Luca and Marie are intertwined in a striking way, revealing to the reader the psychology of each character, including the dog.
