Preliminary Investigation.

Far Eastern policeman Serezhkin, the hero of the movies "The Master of the Taiga" and "The Missing Witness", is now a captain. This time he investigates a complex case of missing rafts with wood, about the fight loggers with foreman Chubatov and a fire at the timber warehouse. All three cases are in one bundle: the intruders are trying to blame everything on the foreman. But Serezhkin is an experienced detective to figure it all out and save an honest man from prison.
