Five fellons are running from justice in search of freedom. During their escape, they run into María Flores who joins them on their journey. They will do what it takes to cross the border and escape a search party that is on their persuit.

The hero, Marcos Navarro, who is part of the five fellons is actually innocent. He was framed by his former employer with charges of murder and theft because he was having an affair with the landlord's daughter.

He escapes his captors and joins other men as they attempt to cross borders. Running thorugh the mountains is their only choice as they have a warrant for their inmediate arrest.
