Belgrade, mid 1920's...One night, the cossack Aljoša kills a priest of the Russian church who found him in the robbery of treasures hidden in the church walls. Young Inspector Stanko Pletikosic gets his first task - to solve this murder together with the inspector and veteran Andrej Tanasijević Tane. Stanko seizes Tane in the bar, and the beginning of their cooperation does not seem to be promising. Cossack officers under the command of the Russian General Vrangel who are stationed in Belgrade, realize that Vrangel's relics have been stolen from the church, but they do not confess it to the police. At the insights of the church, Tane and Stanko seize the bloody message "greeting from Tatko". This message seduces Tane and Stanko, as well as Vrangel's people, on a false track - Macedonian opium smugglers ...
Jedne noći, kozak Aljoša ubija sveštenika ruske crkve koji ga je zatekao u pljački dragocenosti sakrivenih u crkvenim zidovima. Mladi inspektor Stanko Pletikosić dobija svoj prvi zadatak - da to ubistvo reši zajedno sa prekaljenim inspektorom i ratnim veteranom Androm Tanasijevićem Tanetom. Stanko zatiče Taneta u kafani, i početak njihove saradnje, čini se, ne obećava. Ljudi generala Vrangela koji su stacionirani u Beogradu, pukovnik Sorokin i kapetan Fjodor Fjodorovič, shvataju da je iz crkve ukradena Vrangelova relikvija, ali to ne priznaju policiji. Na uviđaju u crkvi, Tane i Stanko zatiču krvavu poruku „pozdrav od Tatka“. Ta poruka zavodi Taneta i Stanka, ali i Vrangelove ljude, na lažni trag - makedonske krijumčare opijuma...
