In search of a missing treasure, Da Silva returns to an old case
Off the island of Barbados, the crew of a Brazilian ocean liner strains to hear the sounds of Carnival coming from shore. A small boat pulls alongside, and a band of steel drummers offer to play for them. As they make their rounds on the ship, the bandleader slips away. He pistol whips one of the crew, forcing him to open the ship's safe, and escapes before the song has ended, taking half a million dollars in gems with him.
The Brazilian police send young detective José Da Silva to investigate the robbery. He captures the thieves but never recovers the jewels. Fifteen years later, three of the gang's members have died in prison, and the fourth is due for release. Da Silva follows him back to Barbados, hoping the thief will lead him to the long-forgotten treasureand a final solution to the case that started his career.
