The year after defeating the Spanish Armada, England retaliates. The expedition to Portugal sets out to destroy what remains of Spain's Atlantic fleet, drive the Spanish out of Portugal, put the claimant Dom Antonio of Aviz on the throne, and seize the Azores. But from the time the English fleet, led by Drake and Norreys, reaches Plymouth, things start to go wrong. Christoval Alvarez, sent to carry out two missions by Walsingham, has a more important private plan in mind. Are any members of the family still alive? And what will become of the disaster-ridden expedition?
