Based on the book Morir Matando by F.G. Haghenbeck, the series follows Lobo Rosales, a former detective marked by his past, whose life takes an unexpected turn when he becomes the protector of Renata, the daughter of the woman he once loved. After an attack leaves her orphaned, Lobo is forced to flee to the border to keep Renata safe and reunite her with her only living relative, only to discover that the girl holds the key to a hidden fortune many are willing to kill for. On their trail is Cruz, a ruthless and corrupt politician who sends in his best weapon: Antonia Lazo, a relentless hunter with a past intimately linked to Lobo. Amid the chase, buried feelings between Lobo and Antonia resurface, forcing them to decide whether to betray each other or save the only pure thing they have left: Renata.
