Mischievously self-assured Mára and somewhat eccentric Heduš set out into the frozen wastes in search of adventure – by car, naturally. After all, Mára’s turning fifteen soon. A road movie about the flies that occasionally buzz around even in winter, and a story that tells of the elusive bond of boyhood friendship and the irrepressible desire to experience something, even if you don't exactly know what.
Unfortunately the movie Winter Flies is not yet available on HBO Max.
