Man on the Train (2002)

Carrying a duffel bag, Milan, a mysterious, stone-faced stranger, gets off a train and sets foot on a small village in the French province. As the man enters a pharmacy, he has a chance encounter with the grizzled retired professor of French literature, Manesquier, and as one thing leads to another, they strike up an unexpected friendship.

And, despite their differences, Manesquier, and his polar opposite, Milan, realise how much they want to be in each other's shoes. One wants to be an adventurer, while the other dreams of settling down. In the following three short days, they will both have to make up their minds.
