Suave secret agent Sterling Archer is the world’s most dangerous spy, but political intrigue and global crises are nothing compared to the sexual tension and human resources crises at the intelligence agency where he works. Archer must deal with his over-bearing, over-sexed mother--who is also his boss--and his femme fatale ex-girlfriend who seems to be sleeping with everyone except him. Embezzlement, mind control, hangovers, and demented double crossings--they’re all in a day’s work in this outrageously raunchy comedy!

In 2009, FX network officially greenlit production of the series, ordering six episodes and an additional four scripts. 
FX originally planned on pairing Archer with the fifth season of the network's situation comedy It's Always Sunny in Philadelphia on Thursday nights believing it would find support among their fans. However, the network learned of the month-long production period needed to create the necessary six episodes, and realized that there was not enough time to have all of the episodes ready before Philadelphia began its new season.
FX instead decided to release a sneak airing of the pilot episode "Mole Hunt" on September 17, 2009, without any promotion or announcement.
ISIS agents head to the luxury winter resort town of Gstaad to protect a German billionaire's daughter from a kidnapping threat. But Archer soon finds out the real threat is his protectee: an underage nymphomaniac who will stop at nothing to bed the world's greatest spy.
Broke after having been wiped out in a Ponzi scheme, Malory decides to sell ISIS to rival spy agency ODIN, whose chief happens to be in love with her. Not surprisingly, the ISIS staff tries to stop the sale---and the romance.
Trinette tries to accuse Archer as to being the father of her baby son, Seamus. Archer tries as much as he can to get out of paying child support if the paternity test passes, but begins growing a bond with the child.
Tired of his colleagues constantly calling him a failure, Cyril agrees to help George Spelvin, a mysterious computer security expert, inject a pirate virus into the ISIS mainframe so Cyril can defeat the virus and be seen as a hero.
Some other changes were noticed by fans of the show. One of the most notable being Archer's skills as the "world's most dangerous spy." In Season 1, his skills as a spy were not showcased very often, so many fans believed he lacked many of the skills. This was proven otherwise with this season's first episode, "Swiss Miss." Here Archer had many opportunities to show that he was a fairly capable field agent.
This season increased the show's focus on the Archer supporting cast. This included adding more frequent appearances by the character of Ray Gillette. Instead of being chained to the ISIS control room, he has now been able to get out and about as an ISIS field agent. Also, details about the backstories of Pam, Cheryl and Doctor Krieger were revealed.
Furthermore, this season saw the addition of numerous two-part episodes. These were episodes in which the broad story was told over two episodes. They didn't follow the traditional television model of adding a "to be continued" tag at the end, but they did end "Stage Two" and "White Nights" on somewhat dramatic cliffhangers.
On a side note, every episode of the second season starts with a character's face at least partially obscured by the TV rating box in the upper left corner of the screen. This was done on purpose by the creator as a protest to a previous accidental incident in which they refused to move the box.
The third season of Archer consists of 13 episodes. FX aired the first three episodes in September 2011 which followed the Sterling's actions after the finale of the second season. The remainder of season 3 continued airing on January 19, 2012. Notable guest actors signed on for the season include Burt Reynolds playing himself as Malory Archer's love interest, Michael Rooker as Sheriff E.Z. Ponder and Bryan Cranston as Commander Drake in the two-part season finale.
The season was initially ordered for sixteen episodes, but Adam Reed mistook the order for the first three episodes in September as part of a 13-episode order.
After the death of his fiance, Archer goes missing for three months. Malory sends a former agent named Rip Riley to find him and bring him back. With Archer's resistance, he ends up stranding them out at sea and mixing them up with pirates.
Archer becomes leader of a pirate island and is enjoying the high life until a disgruntled islander calls mutiny. With Archer, his first mate Noah, and Rip Riley now trapped on the island, Ray and Lana go out to look for him.
Cyril is promoted to field agent, while Malory institutes a strict drug testing policy for her employees. Neither of which sit well with the staff at ISIS. As Cyril is promoted to field agent, he accompanies Sterling and Lana to South America to collect on a bounty of $1,000,000 on Román Calzado. Ray, Cheryl, and Pam know they will not pass the drug test, so they enlist Doctor Krieger to help them pass.
Archer's sex life compromises his effectiveness as an agent. When Nikoli Jackov defects to the United States, he is accidentally killed by Archer's drunken incompetence when he fails to guard the safe house.
One alternate version of the Season 3 DVD cover features an image of Malory sitting cross-legged holding a cigarette and an empty cocktail glass. This pose is directly inspired from an image by acclaimed illustrator Robert E. McGinnis for the pulp noir Kill Now, Play Later.
