Angelo is walking in the grey winter of an anonymous provincial city.
Without love or a job, he spends his empty days in a dreary café in the city's outskirts, day dreaming of a very normal and banal life. Peppino, his father, who never took great interest in his son, is an old man, aware that he doesn'd have much longer to live.
After the death of his wife, Peppino notices his son Angelo, and realizes he knows nothing about him.
"Perfidia" is the story of a father and son that become closer when it has become too late. It is the story od people abandoned to themselves, in great solitude, in a world without pity and without hope, where good people do not exist, and neithr do bad people.
