Die Pantherin.

The night in a big city. A young woman walks alone on a bridge, her gaze unfathomable. She stops, hesitates briefly, then jumps to her death. Under mysterious circumstances, Mara survives the jump and wakes up dazed in hospital. The doctors are strangely reserved when she calls her boyfriend Janis. Mara flees home from the hospital, but finds a completely changed apartment where another woman has taken her place and throws Mara out of the apartment. It slowly becomes clear that no one recognizes Mara, she seems to have completely "fallen out of the world".
