A pretty woman, divorced mother of a child works as a secretary at a research institute. She is taking an external degree. It all looks quite normal. In fact, she experiences serious difficulties: she has a problem with her ex-husband, her child is going through difficult age, a sycophant at the institute is exerting pressure on her, and the jealous wife of her boss makes malicious reports against her. She is forced to fight for each breath and to violate even her own principles in order to survive.

In this picture, the barrier epitomizes the line between reality and dreams, the pattern of harmony and happiness. The delicate, pretty, sensitive Dorotea and the sedate middle-aged composer Antoni meet by chance. He gives her shelter in his house. Famous composer falls under the spell of young Dorothea: A pretty, thin-skinned, though quite an eccentric girl.
