In the eighties, in the Argentine Republic, a young journalist (Joaquín Larson) is induced by the professors of the Miskatonic University to do his thesis, in "exorcisms", in documentary format. The young man travels to the desert to meet two religious experts in exorcisms, who claim to be the guardians of a portal where the bodies and souls of native peoples massacred by the white man are found. Together they will face a demon called Dominom where there will be room for blood, bible and other demons.
