This week we will be transported in Paris, to get to know an isolated immigrant who moves into a gloomy old apartment building where the residents greet him with suspicion and thinly veiled hostility.

Discovering that the previous tenant, a young woman, attempted suicide by jumping from the apartment window, he becomes consumed by her story. Gradually, he begins to see unsettling parallels between her life and his own.

As his paranoia deepens, he becomes convinced that his neighbors are conspiring against him, pushing him further into a spiral of fear and psychological disintegration.
