"There is one thing you must know."
In 3,235 theaters across North America, "Saw II" was playing to packed houses, with many aisles by theater doors crowded with people. The Firefly Films logo flashed across the screen, and the score began with ding-ding-dong-dong sounds, escalating from quiet to loud, bringing an air of mystery and tension with the deep voice of Top-Captain.
A black box was in the center of the cinema screen, inside which lay a girl in a white dress, curled up in slumber. "She is a very dangerous person," Mal, Jayne, Kaylee, and others gaped at the sight of the box; "She holds some secrets you should not know." On a smoky battlefield in the desert, surrounded by terrifying-looking marauders, River's eyes were fierce. Just as her fists clenched to strike, the scene switched to the spaceship's cockpit, the communication screen showing the expressionless face of Top-Captain: "Secrets that could kill Serenity."
