A Serbian soldier named Alex Obilich ventures to Chicago hoping to find his older brother Peter and ask him about a kidney transplant in an effort to save their dad. Peter escaped from Serbia with their mother years ago, leaving behind his brother and father to fight the war – not knowing their fates. Alex desperately searches for his brother, relying on the help of a pretty American named Maria to track him down. What Alex doesn't realize is that their father is actually being used as a tool by a terrorist named Vukasin, who is certain that Peter holds the key to a devastating weapon that his father developed years ago.
