American people across the nation hang on Sneeze's every word. Sneeze is a special correspondent reporting from Mexico, describing the bloody conflict between General Ganache and the rebel El Coyote. When the journalist is captured by El Coyote, President Grant himself sends Lucky Luke south to deliver him. On the spot, Luke finds out that this hack reporter has made the whole story up! He's after glory… but in the meantime, he is kidnapped for real! Two Mexicans have convinced themselves that they ARE the two fictitious characters in question, and live out the exploits in earnest! Aye Caramba! Fiction becomes fact!
