Sometimes a memory can haunt you for a lifetime. A little boy becomes fascinated by whales after seeing the white beluga Aydin on the Youth News. Would he ever see one himself in the Wadden Sea? Only years later, when the boy has grown up, does he come face to face with a beluga on one of his many journeys. The childhood memory of Aydin floats up again: what could have happened to the white beluga? He searches for the truth behind a legend. The Turkish village where Aydin was last seen is still under the spell of the almost mythical white whale. From the fisherman Kemal, the mayor to a mysterious professor: they all enthusiastically tell about the almost magical, but above all true story of beluga Aydin.
