Hong Kong Reporter Doyle Mulligan stumbles onto the biggest and maybe last story of his life. He's investigating the exodus of Chinese from Hong Kong in the months before the handover of the colony to Beijing. The man he's following is a possible ticket-seller on the underground railroad spiriting Chinese out of the city. But when Mulligan follows him aboard a flight to Taiwan, the plane gets blown out of the sky and the ticket seller gets blown out of the plane. One by one Mulligan's leads are eliminated. One by one the people who are smuggling out the Chinese are being murdered by an assassin of almost mythological repute, an unstoppable, unbelievably powerful killer known only as the Yega. The killer is after one man who's already bought his ticket, an eyewitness to the massacre at Tiananmen Square, a witness whose testimony can delay the handover for years.
