Overview:

The trumpet player, Jonah, moves into the remains of his grandfather's house near where the treasure is hidden. In a tunnel under the house he finds a stone with a bird engraved on it and a map with an inscription in Arabic: "To have a house of gold, fall onto the sky and find the twin!" A copy of the same map brings Rumba and Emma to the same place. Rumba is Bulgarian and a passionate treasure-hunter. His wife is American and studies Bulgarian folklore as a way to fight globalization. Rumba wants to buy Jonah's property so he can find the treasure.
