A team of researchers, including a veteran explorer, a best-selling author, and a Vatican-recognized archaeologist, embarks on a quest to uncover the true origins of Christopher Columbus. Challenging the long-held belief that the explorer was born in Genoa, Italy, the team investigates historical documents, maps, and physical evidence, including the potential remains of a Portuguese prince. Their journey takes them across Europe and to Cuba, Portugal, as they piece together a compelling, alternative narrative that suggests Columbus may have been a secret agent for the Portuguese crown, born into a noble family, and that his true identity was hidden for centuries.
