Walker centers on Cordell Walker, a widower and father of two with his own moral code, who returns home to Austin after being undercover for two years, only to discover there's harder work to be done at home. He attempts to reconnect with his children, navigate clashes with his conservative family, and find unexpected common ground with his new partner (one of the first women in Texas Rangers' history), while growing increasingly suspicious about the circumstances surrounding his wife's death.
