The bewitching, blood-stirring and adrenaline-inducing roar of the engine. In general, nothing special for our world. But not for the one in which our contemporary Pyotr Pastukhov found himself. Here it is the mid-twenties of the twentieth century and steam rules the roost in the complete absence of internal combustion engines. Well, don’t call those units that were created by would-be enthusiasts with their own modest funds as such. Why "grief"? So, anyone who tries to encroach on the monopoly of steam engines risks losing his life at the hands of a secret club. It is unknown how all this would have turned out if Peter had known about all this from the very beginning. But now he has no other choice: either he will break the back of the club, or it will roll over him with a heavy roller.
