Just when they were discouraged, the sudden emergence of the army brought them hope of life. But they soon found that the soldiers did not intend to save them, but to kill them. It turned out that the military would do whatever it takes to cover up the incident, including insiders, but they did not expect that the scope of the incident would be so wide.
