TONIGHT’S BEST
The Voice
6 p.m. on (83); 9 p.m. on 13 16
Rock star Gwen Stefani reclaims her red chair alongside fellow superstar coaches Kelly Clarkson, John Legend and Blake Shelton as they return for Season 19 of this four-time Emmy-winning music competition series. Among the new twists this season, in the Battle Rounds, the four artists that were saved by their individual coaches will not automatically advance in the competition. Instead, they must vie in the first Four-Way Knockout. Carson Daly returns as host.
One Day at a Time
7 p.m. on 76 (85); 10 p.m. on 7 12
After Alex (Marcel Ruiz) accidentally catches his mother (Justina Machado) in a compromising position, Penelope decides it’s time to sit down with her son for a talk about healthy human sexuality in “Boundaries,” the first of two back-to-back episodes. That effort is complicated, however, by Lydia’s (Rita Moreno) shocked and judgmental old-school perspective. Then, in “One Halloween at a Time,” Lydia finds something life-altering in the kitchen trash. Todd Grinnell and India de Beaufort also star.
Emergency Call
8 p.m. on (84)
In a new episode called “Crime Spree,” tireless emergency call takers in Austin, Texas, Wasilla, Alaska, and Ogden, Utah, receive a series of bone-chilling — or sometimes just bizarre — calls, including a terrified mother who hears an intruder trying to break into her home; passersby threatened by a gun-wielding and erratic driver creating a six-hour wave of mayhem; and residents of a neighborhood bewildered by the surreal sight of an injured man licking a stop sign. Luke Wilson is the host.
