Season 4 of the acclaimed mockumentary opens with the discovery that Ryan Howard (B.J. Novak) has ascended the corporate ladder from fresh-faced intern to stylishly bearded corporate chieftain. The young gun promptly exercises his authority by charging Dunder Mifflin into the digital age, an affront to technologically dull Scranton branch boss Michael Scott (Steve Carell). Here are the romantic "fax" of life at the office: Jim Halpert (John Krasinski) and Pam Beesly (Jenna Fischer) are hot, Dwight Schrute (Rainn Wilson) and Angela Martin (Angela Kinsey) are not, and Andy Bernard (Ed Helms) and Angela are giving it a shot. A giddy Jam (Jim/Pam) proudly bring their hushed and long-delayed romance to public light, even spending an unsettling night at the Schrute family farm. Dwight confesses to killing Angela's treasured cat Sprinkles, prompting Angela to terminate their romance, which leaves tight Dwight heartbroken and miserable. Angela, in turn, falls into the arms of newest staffer Andy, but only reluctantly. As for Michael, he huffs and puffs through a 5K fun run; hopes to attend a Web-site launch party in the Big Apple; faces a ballooning personal debt; goes on a wilderness survival retreat; butts heads with desk jockey Stanley Hudson (Leslie David Baker); and travels a bumpy-road romance with high-maintenance ex-bigwig Jan Levinson (Melora Hardin), who's mired in a messy wrongful-termination lawsuit with corporate. All this doesn't stop Michael from obsessing over a model in an office-supply catalog or clubbing for "hot hotties" with Ryan in New York. As the year winds down, slumping human-resources drone Toby Flenderson (Paul Lieberstein) decides to quit his post and move to Costa Rica. This development prompts the arrival of a new HR worker named Holly (Amy Ryan), whose sunny presence clearly begins to brighten Michael's downcast world.

This release serves up all 22 episodes from the fourth season of the superhero series Smallville, a program that detailed the high-school years of Clark Kent, Lex Luther, and Lois Lane.

Federal agent Jack Bauer (Kiefer Sutherland) is having a very bad day in this unique, action-packed drama series in which events unfold in real time and the entire season takes place within one 24-hour day. Bauer is the director of the Counter Terrorist Unit in Los Angeles. He's also a married man who is attempting to rebuild a trust-depleted relationship with his wife Teri (Leslie Hope), and a father to independent-minded teen daughter Kim (Elisha Cuthbert). Shortly after midnight on the morning of the California Democratic presidential primary, Jack receives information that an assassination attempt will be carried out against Maryland senator David Palmer (Dennis Haysbert) -- the first African-American with a legitimate chance of capturing the White House -- sometime within the next 24 hours. Jack's mission is made even more difficult when he learns from his boss Richard Walsh (Michael O'Neill) that someone within CTU may be a mole involved with the foreign-based conspiracy. Meanwhile, Palmer, unaware of the assassination plot, receives a phone call from a dogged reporter who says she has evidence that his son Keith (Vicellous Reon Shannon) committed murder. He allegedly killed his sister's rapist. Palmer initiates an investigation to uncover the truth and must decide whether to break the story himself or wait. Jack is contacted by terrorist Ira Gaines (Michael Massee), who informs him that his wife and daughter have been kidnapped by Gaines' henchmen. Gaines threatens to kill them if Jack refuses to follow his detailed instructions. Gaines' goal is simple: Jack is to carry out the assassination against Palmer himself. As the hours pass, the conspiracy deepens, and Jack learns the surprising truth behind the plot and his role in it.

After thwarting last season's attempted nuclear attack on Los Angeles, Day 3 finds Counter Terrorist Unit agent Jack Bauer (Kiefer Sutherland) again fighting to protect the city, this time from a weaponized virus. But Jack is also battling a personal demon---a heroin addiction he picked up while working undercover in a drug-smuggling ring run by terrorist Ramon Salazar (Joaquim de Almeida). At Jack's side throughout Day 3 is his daughter, Kim (Elisha Cuthbert), who took a desk job at CTU in the time between Seasons 2 and 3. Complicating matters is Kim's relationship with Jack's new partner, Chase Edmunds (James Badge Dale), whom she has been secretly dating. Further CTU romance is found between agents Tony Almeida (Carlos Bernard) and Michelle Dessler (Reiko Aylesworth), whose working relationship has blossomed into marriage. But it's a rocky union that's tested throughout Day 3, by everything from charges of terrorism to exposure to a deadly virus. Following the dissolution of his marriage to the first lady, President David Palmer (Dennis Haysbert) is deep into his reelection campaign. But privately he is still grappling with the lingering effects of the viral attack carried out by assassin Mandy (Mia Kirshner) during Day 2's final moments. New to the series is Chloe O'Brian (Mary Lynn Rajskub), a CTU senior analyst whose computer skills prove helpful during Jack's mission this season and beyond. Day 3 also features the first appearance of Wayne Palmer (DB Woodside), who serves as the new chief of staff for his older brother. While lacking in major guest stars, Day 3 does feature Zachary Quinto ("Heroes") as rookie computer analyst Adam Kaufman, and Daniel Dae Kim ("Lost"), who returns for a second go-round as CTU agent Tom Baker.
