Unmarried Couples: A Comedy That Will Break You Up (1997)
Marie and David are always arguing while their friends Sara and Samuel always seem to be happy together. Or are they? This year they decide to spend Christmas in the mountains together.
On a train in 1945 a train conductor is in charge of a motley bunch: a failed author who means well but creates chaos; a soldier who is actually on the wrong train; a doctor who wants to murder his wife; a gay man who hates men; and two nuns with religious doubts.
