The 'Archer' collection is called Codename:Duchess. I will admit, I am not a dedicated fan of the show but my daughter is, and she has been asking me to do this collection for a while now, and has guided me along the way.
Here is the basic story line, taken from IMDb:
At an international spy agency, global crisis are merely opportunities for its highly trained employees to confuse, undermine, betray and royally screw each other. At the center of it all is suave master spy Sterling Archer, whose less-than-masculine code name is "Duchess." Archer works with his domineering mother Malory, who also is his boss. He also has to deal with his ex-girlfriend, Agent Lana Kane and her new boyfriend, comptroller Cyril Figgis, as well as Malory's lovesick secretary, Cheryl.
The origin of the code name Duchess: Duchess was the name of Archer's Mom's dog, who was her most prized possession... She had a portrait made of Duchess and it hangs in her office, and the Codename Duchess was used several times in the series, for the password into the office or for a couple missions.
It's also Archer's alias when he's undercover, or radio name. It's also suspected that Duchess was also Malory's (that's archer's mom) Codename when she was a spy for OSS, but that's just a fan theory and not actually stated in the show because throughout the show, various enemy spies or just spies from different American organizations refer to "Codename Duchess" as the most dangerous spy in the world
