Texas hill country, 1868. As nineteen-year-old Benjamin Shreve tends to business in his workshop, he sees a stagecoach leave a passenger stranded. The man, a treasure hunter, persuades Benjamin to help track down the coach, drawing him into a drama he could never have imagined. On reaching the coach they discover that its passengers include Nell, a pregnant young woman, and her four-year-old son, Tot, who are fleeing Nell’s brutal husband and his murderous brothers. Nell is in grave danger. If her husband catches her, he will kill her and take their son. Benjamin offers to deliver Nell and Tot to a distant port on the Gulf of Mexico, where they can board a ship to safety. He is joined in this chivalrous act by two companions: the treasure hunter whose stranding began this endeavour and a restless Black Seminole who has an escape plan of his own. Fraught with jeopardy from the outset, the trek across Texas becomes still more dangerous as buried secrets emerge. And even as Benjamin falls in love with Nell and begins to imagine a life as Tot’s father, vengeful pursuers are never far behind.
