 A tribe of Mexican Indians in the jungle, commanded by chief Coromoto (Jorge Martínez de Hoyos) live with fear because of the presence of a Spanish colony settled in the outskirts. Coromoto s fears are increased because of the presence of a snake and the prophecies of the sorcerers. His government is threatened by the rebellious character of Piache (Arturo Martínez), a warrior who also has his followers. One day Coromoto and his people have a vision in the lake of the Virgin Mary, but he doesn t trust on it, thinking that it s a negative spirit despite its beauty. However, the tribe exiled a woman, Guaita (Lilia Prado) and his little son Jesus (Paquito Fernández). Guaita and Jesus run away to the Spanish colony, where they re received in the local governor s house (Domingo Soler). The governor and a soldier, Bartolome (Joaquín Cordero) offer to help Guaita and Jesus. Maybe the father of the child is a Spaniard known by Bartolome and his brother.
