Hamilton walks trough the streets of Stockholm, on the lookout for several persons. A series of explosions goes off in what seems like a terrorist attack.
The terrorists of the attack flee through the woods. Hamilton arrives in Sweden after his mission. His arrival is monitored by Kristin Ek. In the meantime DG has made some arrangements after his visit to Russia.
