While Andy deals with the outside world, more than a hundred other souls share an imaginary house inside Andy's head, struggling to maintain an orderly coexistence: Aaron, the father figure; Adam, the mischievous teenager; Jake, the frightened little boy; Aunt Sam, the artist; Seferis, the defender; and Gideon, who wants to get rid of Andy and the others and run things on his own.
Andy's new coworker, Penny Driver, is also a multiple personality, a fact that Penny is only partially aware of. When several of Penny's other souls ask Andy for help, Andy reluctantly agrees, setting in motion a chain of events that threatens to destroy the stability of the house. Now Andy and Penny must work together to uncover a terrible secret that Andy has been keeping . . . from himself.
