A bus and a truck are moving towards each other along a two-way traffic highway on a rainy day.

The epilogue brings some more surprises...

The plot takes place during the Civil War in Greece, and it shows the fight of communist partisans, against the pro-Western, monarchist government. During the shooting, there was a discord between Yugoslavia and the Soviet Union because of the famous IB resolution, which caused Yugoslav authorities to stop supporting Stalinists. Tito's government acknowledged Greek monarchists as a legitimate government, and not wanting to remind the public of their ideological discrepancy, bunkered "Majka Katina" for a few decades.
