The show revolves around a corporation running numerous underground establishments (known as "Dollhouses") across the globe which program individuals referred to as Actives (or Dolls) with temporary personalities and skills. Wealthy clients hire Actives from Dollhouses at great expense for various purposes. The series primarily follows the Active known as Echo, played by Eliza Dushku (who also served as producer), on her journey towards self-awareness.
The story follows Echo (Eliza Dushku), a "doll" or "Active" for the Los Angeles "Dollhouse", one of several fictional facilities run by a company which hires out human beings to wealthy clients. These "engagements" range from romantic interludes to high-risk criminal enterprises. Each Active has their original memories wiped and exists in a child-like blank state until programmed via the insertion of new memories and personalities for each mission. Actives such as Echo are ostensibly volunteers who have surrendered their minds and bodies to the organization for five-year stints, during which their original personalities are saved on hard drives, in exchange for vast amounts of money and a solution to any other problematic circumstances in their lives. Echo is unique however in that she remembers small amounts even after personality "wipes", and gradually develops an increasingly cognizant self-awareness and personality. This concept allows the series to examine the notions of identity and personhood.
