Lara finds a transparent stone on the shore of the Black Sea. A piece of dark glass, which once fell out of glasses and was rolled around by the waves, brings up memories in a woman’s soul that have long been safely hidden in the far corner of her memory. Violence and fear, contempt and resentment, passion and coldness - all facets of a strange relationship twenty years ago, which took a completely different turn than it seemed at first, gradually emerge in Lara's memory.
