He has to go to Lisbon to meet an eminent historian whose work is the subject of his thesis. Having just made up with Claire, he decides to take her along. She's an ideal travel companion and it seems their relationship has not yet exhausted its potential. But moving from Lisbon to Oporto, their fantasy of a second honeymoon clashes with the reality of a world on the verge of a nightmare.
