The weekend highlights include major developments on top dramas.

"The Walking Dead" concludes its fourth season at 9 p.m. Sunday on AMC. The channel hints that Rick (Andrew Lincoln) "comes face to face with sheer brutality." What will we learn about Terminus? Will there be more reunions? Will we see Carol? Lincoln and show runner Scott M. Gimple are guests on "Talking Dead" at 10 p.m. on AMC.

"The Good Wife" follows last week's shocking developments with fury. SPOILER ALERT: In the episode at 9 p.m. Sunday on CBS, Alicia (Julianna Margulies) tries to make sense of a phone call she received from Will (Josh Charles) shortly before his fatal shooting. The episode lets series regulars vent in compelling ways. Christine Baranski as Diane Lockhart, Archie Panjabi as Kalinda Sharma and Matt Czuchry as Cary Agos are all dynamic in their anger. Kalinda's big scene is memorably creepy. (A warning: NCAA basketball could push back the CBS lineup.)

"Resurrection," at 9 p.m. Sunday on ABC, turns to a murder investigation and the hunt for the mysteriously furious Caleb. Another returned-from-the-dead character complicates the pastor's life. A medical checkup reveals more surprises about the resurrected in the small Missouri town.

"Once Upon a Time," at 8 p.m. Sunday on ABC, focuses on Neal's return to Storybrooke and his longing to reach son Henry. The network says Regina finds a possible link to Robin Hood, and Rumplestiltskin's fate figures as another major plot.

PBS joins the busy dramatic contest with the returns of "Call the Midwife" at 8 p.m. Sunday and "Mr. Selfridge" at 9.

"Death Row Stories," at 9 p.m. Sunday on CNN, turns to the case of James Duckett, a former Mascotte police officer convicted of the 1987 murder of 11-year-old Teresa McAbee. It's a strange crime story, even for Florida.

Wynton Marsalis becomes a "60 Minutes" correspondent with a profile of jazz pianist Marcus Roberts at 7 p.m. Sunday on CBS.

Louis C.K. hosts "Saturday Night Live," which is a good reason to tune in. Sam Smith is the musical guest at 11:30 p.m. Saturday on NBC.

The NCAA Men's Basketball Tournament has provided some of the best entertainment this year. The games continue Friday night on CBS and TBS and through the weekend.

"Piers Morgan Live" concludes its bumpy run at 9 p.m. Friday on CNN. Expect more conversation about Flight 370.
