San Francisco 1915. Corto will visit the World Fair and his friend Jack London. Although he is not there, Jack asks Corto for a big favor. An adventurous journey to Dawson City in Alaska begins. There, during the Gold Rush, the Japanese woman Waka Yamada was the most beautiful in the saloon. Strong characters come together, both good and bad people. A few footnotes are also added to world history, and in the end, it all comes back to the treasure that real men chase forever. Not only a tribute to the great master Hugo Pratt but also a worthy continuation of the legendary series.
