An attractive girl gets into the car of a famous composer Antony Manev, claiming that he should take her home. The composer soon discovers that her only home is a lunatic asylum where she has been institutionalised with schizophrenic disorder. Antony takes the girl to his apartment, offers her to copy notes for him and frequently consults with her supervisor in the hospital. The doctor’s intention is to help her patient socialize outside the hospital environment, since she reckons that Doroteya has recovered well enough. However, after being together for more than a year, Doroteya persuades Antony to fly with him over the apartment blocks. They both take off the ground. “Crossing the barrier” creates finally full confidence between them and they make love for the first time. This event astounds the composer so much that he takes a day off, and goes to the mountains to think about it. In his absence Doroteya attempts another flight and is found dead on the next morning quite away from her supposed take-off ground.
