Montana-born Tex dreams of following in his grandfather's footsteps and kayaking down one of the world's last unconquered wild rivers. When he finally gets enough sponsors, Rex heads to South America to tackle the river known as El Furioso. In Columbia he hires seventeen-year-old Myriam Calambás to be his guide. Myriam longs to go to a university, become a reporter, and tell the world what is happening to her world. Can the two avoid the clashes between the paramilitaries who protect the rich landowners and the guerrillas who are supposed to protect the poor? And can Tex achieve his dream?
