El Cometa: After witnessing the arrest of her father for publishing "subversive" material against the dictatorship of Porfirio Díaz, Valentina escapes taking a sack of gold coins with her in order to hand it over to rebel Francisco I. Madero, who is in San Antonio, Texas. That is how Valentina begins a long journey as a member of a traveling circus, where she finds love next to Victor, who, fascinated by the cinematographer, films everything that occurs before his eyes, in times of great political turbulence.
