1) “Chicago P.D.” season-finale, 10 p.m., NBC. The seventh season ends (earlier than planned) with a quietly powerful episode. It starts with trying to catch thugs selling mini-Uzis. There are complications – there usually are – and then the real plot takes over. We won’t spoil any twists, except to say it’s a deep dilemma for Atwater, superbly played by LaRoyce Hawkins (shown here). The advice he gets – from his boss and from an ex-alderman (Wendell Pierce) now in prison – is complex and layered. So is the story.
2) “Chicago Med” and “Chicago Fire” season-finales, 8 and 9 p.m., NBC. Here’s one impact of the virus shutdown — dramas falling short of a 22-episode season. All three of the Chicago ones are stopping at 20 – “P.D.” with a terrific hour, the others with so-so ones. In “Med,” Crockett is suspected of a murder long ago, far away … Choi risks his life … and Charles tries to comfort his teen daughter; most things get resolved briskly. In “Fire,” Sevaride rages when a careless business endangers his crew.
3) “What We Do in the Shadows” season-opener, 10 and 10:30 p.m., FX. No, this isn’t for everyone; vampire comedies rarely are. But many people will find it hilarious. These vampires have been in Staten Island for a century, without doing much. Guillermo (the terrific Harvey Guillen) has been their assistant (called a “familiar”) for a decade, and secretly kills attacking vampires. That makes the opener very violent … and very funny, especially with Haley Joel Osment as a second familiar.
4) “Lego Masters” finale, 9:01 p.m., Fox. With no elimination last week, three duos are going for the $100,000 prize. Mark and Boone (bad-beard buddies) have won four of the nine rounds and never been in the bottom two; Sam and Jessie (friends) have zero wins and four times at the bottom. Tyler and Amy (young married) have three wins, but last week hit the bottom for the first time.
5) And more: At 8 p.m., Fox’s “Masked Singer” pauses for a “sing-along” edition, with lyrics appearing along with past performances. At 9, PBS has a two-hour look at the American surge of diabetes; also, the unexceptional “American Housewife” takes over the ABC timeslot of the great (and now departed) “Modern Family. And today, Hulu has the first three episodes of “Mrs. America,” an FX production that’s richly crafted, telling the story of people pushing to pass or stop the Equal Rights Amendment.
