1) “Call the Midwife” finale, 8 p.m., PBS. For 15 years, this has given us good people in awful situations. Now that’s sort of ending; plans call for a feature film, a prequel series and (possibly in a couple years) some of these characters in a new setting. For now, there are deeply moving stories about the Rosalind/Cyril romance (shown here in a previous episode and Sister Monica Joan’s health.
2) More finales. “The Count of Monte Cristo” (10 p.m., PBS) slogs to its finish, mostly reminding us that revenge really isn’t much fun. On a lighter note are two HBO shows: “Rooster” ends its first season at 10; “The Comeback” has its series finale — three seasons, over 21 years — at 10:30.
3) “Tracker,” 9 p.m., CBS. Sofia Pernas — the real-life wife of star Justin Hartley — is back as his sometimes-competitor, Billie; tonight, their cases seem to entwine. That follows a “Marshals” that finds Kayce and Cal stranded in a blizzard with a fugitive.
4) “Audacity,” 9 p.m.,, AMC, rerunning at 10:20. Disparate characters are beginning to collide in intriguing ways: Two troubled teens are in one’s secret hide-out … His mom– an insider-trading therapist, desperate to keep her house — faces Duncan …. And Duncan and his ex-lover have a spectacular board-room confrontation. It’s a big, busy episode.
5) ALSO: “MaryLand” starts a four-week rerun on PBS; it’s an excellent tale of sisters who find surprises after their mom’s death. And Turner Classic Movies spends this Mother’s Day with films about moms, including “Gypsy” at 5:30 p.m. ET; then it has “Gone With the Wind” at 8.
