The four Swedish soldiers Forss, Babic, Strand, and Kilpinen attempt to open the Mario Road and are shot at. Their squad leader Johansson is killed. A difficult time begins for the young soldiers. Forss is appointed the new squad leader by Colonel Andreasson. Is the young diplomat candidate up to the task? Meanwhile, the village of Stupni Do is attacked by the Croatian Defence Council (HVO), and smoke can be seen in the distance. The squad led by Forss is sent out to assess the situation. But the Croatian Bosnians have set up roadblocks and are denying them access to the village... Tensions between the various parties are high.

Life at Camp Valhalla continues: Babic is the new troop commander, Forss has been invited to an interview for the Swedish diplomatic program, Kilpinen is spiraling deeper into his morphine addiction, and Strand is falling in love with Alma. The young UN soldiers have been given a day off by Colonel Andreasson. Most of them are playing soccer, but Strand prefers to go swimming with Alma. They drive to a lake, and it seems as if time stands still. But the war rages on, and civilians of various backgrounds are being harassed and bullied. Colonel Andreasson has to negotiate with all sides, which he clearly doesn't like. The negotiations prove more difficult than expected.
