In a first-class compartment, Kamo is carrying dynamite for the rebellious workers. In Tiflis, portraits of Kamo are plastered on the walls of houses. A large reward is promised for his capture. However, nothing can stop the daredevil. Under the leadership of the Russian Bolshevik Vasily, he organizes a workers' militia and, together with it, performs a series of feats.
