Set in New Iberia, La., a Southern city with a strong history of racial tensions, this new two-hour documentary chronicles a crusade for justice by the family of Victor White III, who died under mysterious circumstances on March 2, 2014, while in police custody.

7 p.m. on ABC The Bachelorette

The moment of truth arrives for Becca Kufrin — and the stakes are big, since she knows from “The Bachelor” what it’s like to be chosen and then “unchosen” — as she picks between the two finalists in the conclusion of this series’ 14th season. Two men, one rose: That’s the math as Kufrin decides which man is the one she most wants to be with. Chris Harrison is the host of this three-hour presentation, which includes the traditional “After the Final Rose” special.

8 p.m. on CBS Salvation

Darius (Santiago Cabrera) is determined to stop the hackers collectively known as ReSyst, whatever it takes, in the new episode “The Madness of King Tanz.” Grace and Harris (Jennifer Finnigan, Ian Anthony Dale) both deal with secrets. Taylor Cole appears in her recurring role.

8 p.m. on NGEO Yellowstone Wolf Dynasty

This new docu-series presents a rare environmental “good news” story that delivers a potent message about how important it is to keep ecosystems in balance by looking at a groundbreaking program in 1995 that reintroduced wolves to Yellowstone National Park. In the 20-plus years since, those wolves — imported from Canada and known as the Druid Peak Pack — revitalized the area. The opening episode, “The Pack,” introduces some of the diverse lupine members of that group.

8 p.m. on AMC Lodge 49

Erstwhile surf bum Sean “Dud” Dudley (Wyatt Russell, Black Mirror) has been feeling at loose ends since the recent death of his father and the collapse of their family business in this darkly comedic new “modern fable.” Seeking a new sense of direction, he joins a rundown fraternal order, where middle-aged plumbing salesman Ernie Fontaine (Brent Jennings), a “Luminous Knight” of the lodge, welcomes him into this new world of mystic fellowship. Sonya Cassidy, Linda Emond and Eric Allen Kramer also star.
