Imam Hasan, his wife Hacer and his daughter Fatma arrive at Karaağaçlı, a small railway town in the middle of the Anatolian wilderness. Besides carrying out the duties of the imam, Hasan will be teaching religion to the children of the town during the holy month of Ramadan. His unusual behavior towards his wife and little daughter arrests the attention of the townsfolk. Meanwhile Adem, the son of the stationmaster who is crazy for trains begins to learn about and get into a world he has never heard of before in the lessons given by Hasan: trains, sin, good deeds, heaven and hell.. everything gets jumbled. Condemned of being harsh and merciless towards his family, Hasan one day finds himself obliged to reveal the "secret" about himself and his family and this changes everything in the eyes of people. Yet there has remained another secret of which anyone, even Hasan is hardly aware. The people of the town, including Adem, will remember this Ramadan throughout their lives.
