Plot summary

Alex and Peter are brothers from Serbia. Peter left the country years ago with their mother, while Alex stayed behind with their father and fought in the war. The two have not seen each other since. Alex believes their father is near death and needs a bone marrow transplant, so he leaves Serbia for Chicago to find Peter. An American CIA operative helps him locate his brother there, and the estranged pair meet again. Their father once developed a chemical weapon for the Soviets, and a terrorist named Dreq wants it, believing Peter can help him obtain it. Alex is also in love with a young Muslim woman, though the relationship is forbidden. He asks Peter to come back to Serbia with him.
