1) “Boston Blue,” 10 p.m., CBS. Back from a nine-week break, here’s a potent hour. Jonah, a rookie cop, was on a solo mission to avenge the murder of his dad, a judge. That creates a fresh crisis; at the shooting scene (shown here),Jonah’s family must step aside, with Danny and Sean taking over. The result is what “Boston Blue” thrives on — a mixture of tough, cop-show action and family emotion.
2) “Sheriff Country,” 8 p.m., CBS. Before the long break began, Sheriff Mickey Fox arrested the patriarch of the Barlow clan. Now her jailhouse is under siege and her ex-husband is near death. It’s a strong action hour, leading into a “Fire Country” probe of a deadly blaze. Add “Boston Blue” and you have a high-octane return for CBS.
3) “Stumble,” 8:30 p.m., NBC. Last week, this rag-tag cheer team landed a spot in the national competition in Daytona. To compete, however, it must add four people. The result is uneven, but has some great moments; it follows an OK “Happy’s Place” that, alas, again dumbs down two of its characters.
4) “Great Performances,” 9 p.m., PBS. Fresh from her sixth Grammy (best jazz vocal album), Samara Joy makes her Royal Albert Hall debut. Joy, 26, sings the classics, including “Misty” and “Day by Day.” That’s followed by a rerun of an excellent profile of Hazel Scott, a pioneering pianist and singer.
5) “Paul McCartney: Man on the Run,” Amazon Prime. After nearly 10 years as a Beatle, McCartney did another decade with Wings. This documentary wraps a streaming week that has “The Bluff” and “The Gray House” (Prime), the second half of the “Bridgerton” season (Netflix) and season-openers of “Paradise” (Hulu) and “Monarch: Legacy of Monsters” (Apple).
