Niko and Otar are assigned to work at the winery. Ambitious Otar becomes subservient to the director of the winery from the beginning, whereas Niko stands up against the illegal activity in the winery. He opposes the unlawful drain of the alcohol and the bottling of the adulterated wine in order to fulfill the plan. For that purpose Niko adds to the wine a cleaning chemical and hampers its bottling. The director and his corrupt subordinates get indignant, but refrain to punish Niko.
