Persona Non Grata is the epic story of Frans Wuytack's life. After thirty years of exile, he returns to South-America with his son, film director Fabio Wuytack. Their overwhelming journey reveals the Venezuelan slums, where Frans unchained a social and cultural revolution as a young priest in the 1960's. A blend of humorous and touching characters from the slums take Fabio on a voyage through the maze of his father's exciting past. The poetic film style lifts the story over the borders of a biopic and confronts us with some of the most important moments in the second half of the 20th century.
