no TopFlix. A young engineer named Zotov has been appointed head of the 406th picket line at the construction of a railway line in the taiga. The construction workers huddled in a smoky, dark dugout did not welcome the new foreman very cordially: not everyone can do hard work and household disorder.

And again it's weekdays, and again the cold barracks is full — a new batch of builders has arrived.
