The Trans-Iranian Railway runs roughly 1,400 kilometers from the Persian Gulf through Tehran to the Caspian Sea, and this film rides it end to end at a moment when Iran is only beginning to let in foreign travelers again. The camera follows the journey through the changing landscape outside the windows, from arid southern plains to the greener slopes near the Caspian coast, while stops along the way open onto bazaars, mosques, and the daily routines of people who live along the line. Conversations with locals and fellow passengers fill in what guidebooks leave out, covering food, faith, and the practicalities of getting around a country still largely closed to Western tourism. Archival context on the railway's construction, one of the major engineering projects of Reza Shah's modernization drive, sits alongside the present-day footage. The film treats the train less as transport than as a way to see a country that most viewers have never had the chance to visit directly.
