Queen Sugar (10/9c, OWN): Settling into its regular time period in the second half of the series premiere, directed by Ava DuVernay (Selma), Sugar finds bittersweet tidings in family dynamics as sisters Charley (Dawn-Lyen Gardner) and Nova (Rutina Wesley) clash while planning their father’s funeral, and brother Ralph Angel (Kofi Siriboe) is accused by formidable Aunt Violet (Tina Lifford) of coddling his young son Blue (Ethan Hutchison) when he debates whether to take the boy to the service or leave him with his overwhelmed mom, Darla (Bianca Lawson). This isn’t a show to watch so much for plot as for feeling, and in that regard, this Queen excels.

Commander in Chief Forum (8/7c, NBC): As a warm-up to the much-anticipated presidential debates that begin later this month, Matt Lauer moderates a “joint candidate event” from aboard the Intrepid Sea, Air & Space Museum in New York. Contenders Hillary Clinton and Donald Trump will take questions about military and veterans’ issues and national security from an audience of service members and veterans.

Nova: 15 Years of Terror (9/8c, PBS; check local listings at pbs.org): TV’s leading science program explores how terrorism has grown and evolved through technology in the years since the 9/11 attacks, including the use of social media to recruit a new breed of zealot with targeted propaganda.

Inside Wednesday TV: The conclusion of Discovery’s Harley and the Davidsons (9/8c) finds America in the throes of the Great Depression, which doesn’t keep the motorcycle entrepreneurs from revving up their business. … A third season of Audience Network’s Full Circle (9/8c, DirecTV and AT&T U-verse) takes on a political theme, with interlocking stories set against the Democratic primary in Miami. The cast includes Covert Affairs’ Christopher Gorham, Lost’s Harold Perrineau and 24’s Kim Raver. … With Mike (Patrick J. Adams) finally freed from prison on USA’s Suits (9/8c), the focus now falls on protecting him from vengeful inmate Frank Gallo (Paul Schulze), while Jessica (Gina Torres) and Rachel (Meghan Markle) reopen their death-row case. … On USA’s mind-teasing Mr. Robot (10/9c), Elliot (Rami Malek) is now wondering if Mr. Robot (Christian Slater) has been keeping the full truth from him again. What are the odds? … The two-hour finale of CBS’s American Gothic (9/8c) finds the family on Election Day still trying to figure out which of them is the killer. The show is promising a major death, but given that CBS hasn’t yet renewed the show, fans will settle for a solution.
