While visiting Toledo, Spain, American tourist Lisa Reiner (Elke Sommer) experiences a feeling of deja vu when she sees an ancient mural of the Devil carrying away the dead. Hearing a familiar melody, she wanders away from her companions into a series of encounters with men who inexplicably recognize her from a past life.
