Irons is hired by an underworld fixer in Croatia by the name of Georg Rudek to steal a laptop from RCAF Brigadier-General Malcolm Lennart, who is currently stationed in Bosnia. This is the sort of job Irons specialises in.
After carrying out some surveillance on the target, Irons stages a fire at his favourite restaurant and takes advantage of the confusion to switch over the laptop with a pre-prepared duplicate. He then goes to exchange the laptop with his buyer, Anton Dedopovic, at a graveyard in Serbia, and is ambushed. Irons is prepared for this, and has engaged Stanislav Nevenovic, a Balkan assassin he has previously worked with, to provide him with fire support, as well as rigging the meeting site with remote-controlled claymore mines. This foresightedness leads to a massacre of Dedopovic and his men.
In order to identify who tried to betray him, Irons murders his way though the Nasa Stvar (aka the Serbian mafia) in Belgrade, eventually tracking down the head of their cigarette smuggling operation, Danilo Brigovic aboard his party barge. After some more murder and a spot of torture with the assistance of Anya Ivanova, a former Russian agent, Irons discovers the man behind the whole operation, a Romania staying at a hotel in Belgrade.
Irons infiltrates the hotel in an attempt to interrogate the Romanian, managing to kill his bodyguard but failing to capture his target who escapes with a display of supernatural power (spiderclimbing across the ceiling and out of the building). He does manage to recover several documents relating to the Black Sea Bank from the Romanian’s safe before bugging out of Belgrade and fleeing to his safe house in Germany.
