What’s on TV

I AM THE NIGHT 9 p.m. on TNT. This mini-series draws from the life of Fauna Hodel, an author who, after learning she was adopted by African-American parents, discovered that one of her grandfathers was George Hodel, a prime suspect in the unsolved Black Dahlia murder of 1947. But the rest of the story is largely fiction, and “the result is a bland hodgepodge,” Mike Hale wrote in his review in The New York Times. Chris Pine, as Jay, a journalist who clings to Fauna (India Eisley) for his own reporting, may be the show’s strongest asset. In this series finale, the Watts riots erupt in Los Angeles as Jay sits in a cell and Fauna desperately searches for a way home.

AMERICA’S HIDDEN STORIES 8 p.m. on Smithsonian. The Smithsonian channel claims to shed new light on pivotal moments of American history with this series. In the first episode, scholars scour old documents and use 3-D computer mapping techniques to uncover the site of the 17th-century Salem witch trial hangings. Later episodes highlight the Spanish influenza of 1918, the treason of Benedict Arnold and a spy ring involved in the Pearl Harbor attack.
