The childhood of a sixteen-year-old dreamer was spent in a shack with an always-drunk father. The only joy for the boy was walking to the pier, where he imagined himself as the captain of a brigantine sailing across the distant and mysterious sea. One night, he secretly left home and sailed away on a steamship, embarking on a journey filled with romantic and beautiful adventures. This marked the beginning of the unfulfilled journey of the writer Alexander Grin.
