In the fall of 1913, society writer Louisa Delafield suffers from panic attacks because of her recent abduction. When her assistant Ellen Malloy wants Louisa to help her find a missing teenager, Louisa finds she’s paralyzed by her earlier trauma. Taking a trip out west in the company of a lovely young heiress to interview the Prince of Monaco only makes matters worse. Even in the pristine wilderness, a procurer is stealing girls for the purposes of sex trafficking. The only way Louisa can overcome her debilitating attacks is to find and stop this man while Ellen goes back into domestic service to protect the heiress from him.
