In the city, Tintin is framed as a terrorist, arrested, and sentenced to death by firing squad. Tintin survives when a revolution topples the government, and the new leader, General Alcazar, appoints Tintin to be his aide-de-camp. Alonso and Ramón capture Tintin, and interrogate him in the hope of locating the missing fetish, but they only end up briefly put behind bars by him. As aide-de-camp, Tintin opposes the proposed decision of San Theodoros claiming the supposedly oil rich Gran Chapo, as this would cause a war between San Theodoros and neighboring Nuevo Rico, and he is framed as a traitor by warmongering oil and weapon companies. Nevertheless, Tintin's new friend Pablo frees him from imprisonment, allowing for Tintin to flee to Nuevo Rico. However, in the process, he inadvertently causes events that, partially as its government considered claiming Gran Chapo for its oil as well, have Nuevo Rico start a war between it and San Theodoros. Once within Nuevo Rico, Tintin decides to enter the forest and find the Arumbaya tribe, hoping they can explain to him why people wish to steal the fetish. Finding a British explorer, Ridgewell, living among the Arumbaya, Tintin learns that a diamond was hidden inside the statue.
