Pretty Little Liars
In a new episode called "The Bin of Sin," Hanna (Ashley Benson) has a strong suspicion that Alison (Sasha Pieterse) is setting her up to take the fall for Mona's murder, but that doesn't mean she's just going to sit back and wait for that to happen. As Caleb (Tyler Blackburn) tries to come up with a way to help Hanna, Aria (Lucy Hale) spills the beans to Ezra (Ian Harding), while Spencer's (Troian Bellisario) dubious actions threaten to get Toby (Keegan Allen) in trouble at work.
David McCallum gets the spotlight in his regular role as Ducky -- though he shares the part with guest star Adam Campbell, who plays it in flashbacks -- in "So It Goes." Accompanied by Ellie (Emily Wickersham), the medical examiner goes to London on a case linked to his best friend from childhood (guest stars Alice Krige and Hannah Marshall, also splitting the role between past and present). Ducky mulls how his decisions have affected his life.
Former "Smash" regular Andy Mientus plays Dr. Wells' (Tom Cavanagh) former protege -- now his enemy -- in the new episode "The Sound and the Fury." The one-time pupil uses sound as his weapon in seeking vengeance. Iris (Candice Patton) gets a reporting job ... and a difficult colleague (guest star Roger Howarth). Joe (Jesse L. Martin) tries to keep a request he's made of Eddie (Rick Cosnett) from Barry (Grant Gustin). Danielle Panabaker also stars.
At times, some people might wonder just what they have in their pantries -- and that's also a question for the young cooks in one of the challenges posed by the new episode "Junior Edition: Raw Talent." The contestant who locates the most of the needed ingredients will be the winner of that round. Later, the entrants pair up in a team competition involving sushi. Gordon Ramsay is the host and, along with Joe Bastianich and Graham Elliot, a judge.
Parks and Recreation
Are the secrets of Pawnee residents safe? Leslie and Ben (Amy Poehler, Adam Scott) fear they aren't, certain that people's privacy is being threatened, in the new episode "Gryzzlbox." Tom (Aziz Ansari) assists Andy (Chris Pratt) with a contract, and April (Aubrey Plaza) tries to set the new interns off on the right foot. Nick Offerman also stars. Another episode follows.
The series arrives in the third city on its itinerary this season, the one of brotherly love, in the new episode "Philadelphia -- Franklin Institute." One Philly resident discovers that the reason his family moved there also affected a great many other people. Another man learns whether he's descended from Vikings, while yet another thinks he may be related to one of those who signed the Declaration of Independence.
Marvel's Agent Carter
The sudden reappearance of Howard Stark (guest star Dominic Cooper) could mean big trouble for Peggy (Hayley Atwell) in the new episode "The Blitzkrieg Button." The reason he shows up again is mystifying -- and also potentially dangerous. Another peril is posed to Peggy by Chief Dooley (Shea Whigham), whose curiosity could result in the end of Peggy's career. Lyndsy Fonseca and Bridget Regan also guest star.
Switched at Birth
Emmett (Sean Berdy) pays a surprise visit to Bay (Vanessa Marano), but it only makes her feel forced to maximize the short time they have together in the new episode "We Were So Close That Nothing Used to Stand Between Us." Elsewhere, Daphne (Katie Leclerc) is mortified when she blows her midterm exam, while Melody (Marlee Matlin) clashes with John (D.W. Moffett) after he urges Travis (Ryan Lane) to try out for the baseball team.
NCIS: New Orleans
While investigating the murder of a chief warrant officer, Pride (Scott Bakula) and his team discover that the victim's wife has been abducted and held for ransom -- which is due in only 22 hours. Senior FBI Agent T.C. Fornell (recurring "NCIS" player Joe Spano) assists with the case. Rocky Carroll and Gabriel Olds guest star; Lucas Black, Zoe McLellan, CCH Pounder and Rob Kerkovich also star in "It Happened Last Night."
You never know what you might find on the Internet, as Sam (Jared Padalecki) discovers anew in the new episode "There's No Place Like Home." He sees video footage of what appears to be Charlie (Felicia Day) assaulting a prosecutor, and Dean (Jensen Ackles) believes there's more to it -- such as the lawyer being a demon. The Winchester brothers are surprised when they learn the truth.
In her role as vice principal, Jess isn't happy when Coach's (Damon Wayans Jr.) affair with the school nurse (guest star Erinn Hayes) takes a nasty turn in "Landline." As a result, Jess declares that faculty members can't get personally involved with one another. When a science teacher (guest star Julian Morris) then attracts her, she wishes she hadn't made that decree. Angela Kinsey ("The Office") also guest stars.
Director Spike Jonze earned an Oscar for his original screenplay for this clever 2013 comedy-drama about a relationship between a man and ... a computer system. Joaquin Phoenix plays a professional letter writer whose equipment upgrade has a voice (that of Scarlett Johansson) and a soul, apparently. That leads them to bond emotionally. Amy Adams, Rooney Mara, Olivia Wilde and Portia Doubleday portray the flesh-and-blood women in the fellow's life.
