Los pájaros no tienen vértigo (Birds have not vertigo)

The director of the film suffers from a vertigo attack in a hot air balloon. From that point on, an investigation begins in which he delves into his personal universe to try to understand his new phobia. But he encounters an added difficulty: he is afraid of exposing himself in public. Therefore, he creates an alter ego that will help him to mask himself throughout the story. Although his strategy doesn't come out as expected.
