Alentejo Blue is the story of the Portuguese village of Mamarrosa told through the lives of those who live there and those who are passing through: men and women, children and old people, locals, tourists, and expatriates.
An old man reflects on his long and troubled life in this beautiful and seemingly tranquil setting, and anticipates the return of Marco Afonso Rodrigues, the prodigal son of the village and a symbol of this now fast-changing world.
The homecoming is the subject of much speculation, and when Marco does finally appear, villagers, tourists, and expatriates are brought together and jealousies, passions, and disappointments must inevitably collide.
