Watch The Son Online at Couchtuner. Based on Philipp Meyer’s acclaimed novel, the multigenerational epic will follow two concurrent time periods: One, the story of young Eli McCullough after he is kidnapped and indoctrinated into a tribe of Comanches in 1849. The other, 60 years later, when we see a grown Eli struggle to maintain his family’s cattle empire during the turbulent Bandit Wars of South Texas. Actor Pierce Brosnan will play the role of Eli, the charismatic patriarch of the McCullough family who applies the brutal Comanche worldview to his business dealings. Born on the day Texas became an independent Republic, “The First Son of Texas” is a relic of the Wild West, uneasy with the inexorable taming of Texas and the uncertain future of his legacy.
