Didi, the Treasure Raider(Didi, o Caçador de Tesouros)

Didi works as a butler at Pedro's father's house. While browsing an old photograph album, he and 10-year-old Pedro find an ancient map with the route to a treasure. They decide to search for it. But the treasure carries a curse cast by the three thieves who had stolen it first, during WW2.
