Susanna, Lady Appleton, is passing time with her new love, Nick Baldwin, in Hamburg when she is approached by her old friend Walter. Distraught over the discovery that his late wife, Eleanor, was conspiring in a plot to overthrow Queen Elizabeth and replace her with Mary, Queen of Scots, Walter beseeches Susanna to help him foil the plot.
