It is the 28th of June, 1914. During a visit to Sarajevo, Franz Ferdinand (heir to the Austro-Hungarian throne) and his wife (Sophie) are assassinated. The archduke's death will become a precipitating cause of World War One.
In this video clip—from a documentary combining historical footage and recreated scenes—meet Gavrilo Princip (part of a terrorist gang called "The Black Hand Society"). He, and others like him, are upset that Greater Serbia does not have self-rule.
Princip is nineteen years old and dying of tuberculosis. The Austrian Empire rules his country, and the young man's anger about that fact is directed toward the heir of the Austrian throne, the Archduke Franz Ferdinand.
Knowing he will soon die of his illness, Princip is not afraid to kill the target of his anger.
When the first would-be assassin is unable to meet his objective, it appears that Franz Ferdinand and Sophie have escaped death at the hands of terrorists.
Then ... the royal couple's driver makes a wrong turn.
