The two boys in their teens travel by car. The journey of boys, who are full of curiosity about sex and wearing fake guns and camo coats, is ludicrous but somewhat adorable. They even imitate the behavior of adults, such as showing off their sexual ability while riding a woman in a car, but it is the police station in the Czech Republic where they end up. With the actors' exceptional performance, Winter Flies proves to be one of the best recent coming-of-age films, intersecting the friendship of the youth and the excitement of adventure.
