He tries to illuminate the world... one light bulb at a time

Henri was raised by religious in a convent and lived with them until the women, now elders, moved, leaving him alone. Henri fixes lamps. Since his young age, he's been replacing burned light bulbs and illuminates people's lives. After following signs, he finds himself working in a lamp company. Through his new work, he meets an old man trying to never forget his glory days and a blind woman, teller in an adult cinema, with whom he falls in love.
