Plot synopsis: Honzík has to spend his holidays with his grandfather because his divorced mother is very busy. However, she doesn't want her father, a former military pilot, to tell her grandson anything about airplanes. She doesn't like airplanes because her childhood memories are mostly of her father constantly being at the airport, and when her mother died, she had to take care of everything herself. The film is about the love of flying. A love that brings both joy and pain in equal measure. It is a story about searching for lost relationships. About building new trust between loved ones. About the permanence of certain values that we often wastefully overlook, not out of malice, but because we take them for granted. The entire film is interwoven with unique real footage of MIG21 fighter jets, the likes of which have never been filmed before and probably never will be again. Other flight scenes feature a number of beautiful machines, from historic gliders to the L159 ALCA.
