No Smoke Without Fire (1974)

Gummat, a rural firefighter, lives in one of the collective farms of Turkmenistan. He is a kind, honest, selfless man who has preserved the purity and integrity of his soul until adulthood. He is very conscientious about his duty and trains his team, Besher's son and Shukur's watchman, according to all the rules of fire science.… A flighty neighbor, Gazelle, constantly whispers to him about thieves and grabbers who rob collective farm goods. The good Gummat can't believe it for a long time — until he agrees to look into the barn of the warehouse manager Batman. And then Gummat does everything to expose the fraudster.
