The harrowing story of a man with no memory--Jason Bourne--an assassin hunted by unseen armies for reasons he doesn't remember. A shooting victim, suffering from amnesia, finds himself with a Swiss bank account in the name of Jason Bourne, a professional assassin being manipulated by a top-secret American government organization to kill his arch rival, the dreaded Carlos. He was dragged from the sea, his body riddled with bullets. There are a few clues: a frame of microfilm surgically implanted beneath the skin of his hip; evidence that plastic surgery has altered his face; strange things he says in his delirium, which could be code words. And a number on the film negative that leads to a bank account in Zurich, four million dollars, and a name for the amnesiac: Jason Bourne. Now he is running for his life. A man with an unknown past and an uncertain future, the target of assassins and at the heart of a deadly puzzle. He's fighting for survival and no one can help him - except the one woman who once wanted to escape him.
