The romantic adventures of two lovers, by the will of unforeseen circumstances, connected by indissoluble bonds, take place in the middle of the last century in America after the Mexican War, during the years of global migration of the population to the West through the scorching prairies. In addition to the elusive Indians, wandering herds of bison, the scorching sun and exorbitant difficulties on the way, the lovers are threatened by cruel captivity, the inevitable danger of death and - the worst thing - the loss of each other.
