In Los Angeles, Jennifer Narody is having a series of disturbing dreams involving eerie images of a lady in blue. She doesn't know that this same spirit appeared to leaders of the Jumano Native American tribe in New Mexico 362 years earlier, linked to a Spanish nun who had the power to be in two places simultaneously. Meanwhile, journalist Carlos Albert stumbles upon a nearly forgotten seventeenth-century convent in Spain founded by this same legendary woman. Intrigued by her rumored powers, he delves into finding out more. These threads, linked by an apparent suicide, eventually lead Carlos to Cardinal Baldi, to an American spy, and ultimately to Los Angeles, where Jennifer Narody unwittingly holds the key to the mystery that the Catholic Church, the U.S. Defense Department, and the journalist are each determined to decipher.
