Amós (Carmelo Gómez) is a humble sailor and boat operator. He excitedly awaits the arrival of an uncle of his who is returning to Spain after being exiled in the Soviet Union since the Spanish Civil War (1936-1939). But they never meet because the old man unexpectedly dies. Amós suspects from the letters his mother received that his uncle was keeping something of great value but he can't find it in his relative's belongings. He begins to investigate and soon discovers that it is a painting by Pablo Picasso. The painting is used as a guiding thread of the film that, in addition to its economic value, Amós searches for its sentimental importance.—TomWins
