Upon arriving in Pintan, Arizona, Jillian Danvers is confronted with the magnitude of the task before her. Though an exact reflection of her twin, Judith, assuming her sister's identity is anything but easy. Not only are her attempts to fumble her way through the strict regulations and routines of the Harvey House feeble at best, Jillian finds she must also fend off the well-meaning acts of matchmaking on the part of her mother. Inadvertently discovering her secret, Dr. MacCallister is drawn to Jillian and her sweet innocence.
