The Turkish superspy (Goksel Arsoy) successfully eliminates an enemy agent before flying off to London for a well-earned vacation. Back in Istanbul, assassins liquidate one of Altin Çocuk's (Golden Boy's) fellow agents, S-99, resulting in the superspy being recalled to duty. Megalomaniac Demetrius (Altan Gunbay) plans to destroy Turkey by smashing a series of remote-controlled warheads into Istanbul's nuclear power facility. Only Altin Çocuk can stop him but the superspy's game plan seemingly goes awry when Demetrius cleverly employs the talents of a very special undercover agent. (In Turkish language, with English subtitles).
