Echo est envoyée pour un engagement en tant que nouvelle épouse de Martin Klar, riche financier lié à une ancienne affaire concernant le nouveau gestionnaire d'Echo que l'ancien agent du FBI Paul Ballard a été incapable de résoudre. Lorsque des liens vers un réseau de contrebande d'armes sont découverts, Paul sait que leur seul espoir d'évasion est d'une manière ou d'une autre de tromper Echo en assumant la personnalité d'un ancien engagenment : un meurtrier expert en art martial. Pendant ce temps, le Dr Saunders lutte avec sa découverte qu'elle est une Doll et cible Topher.
Six months after Alpha's reign of terror and with him still on the loose, Echo now begins randomly picking up flashes of past engagements which hampers her latest assignment when she weds a British businessman client who has ties to one of Ballard's open FBI cases. DeWitt makes Ballard an irresistible offer to join the staff of the Dollhouse, which he's more than happy to agree to. Meanwhile, Topher and his assistant Ivy become the target of Dr. Saunder's anger and aggression after she finds out that she is actually a former Active named Whiskey... imprinted with the real Dr. Saunder's mind. Elsewhere, Boyd takes on a risky venture outside and mixes business with pleasure when he asks Dr. Saunders out on a date. While Victor struggles to deal with his nearly fatal encounter with Alpha, Echo now has her old memories of 'Caroline' now mixed in with every imprint she now takes in and she willingly agrees to help Ballard to take down the Dollhouse from within. Elsewhere, a dogged senator, named Daniel Perrin,begins investigating the Rossum Corporation, the Dollhouse's main benefactor, in order to search for a cos piracy linking it to medical imprint tests.
