Cold War (2012)

In the safest city in Asia, the Hong Kong police department has been untouchable for years--until one night the police headquarters receives an anonymous call after a fully-loaded police van carrying five-highly trained officers and equipment disappears off the grid. After receiving several cryptic phone calls from the hijackers, one officer realizes that they're aware of every crucial decision they make. But as they execute a carefully-planned attack, little do they know they've become unwitting pawns in a bigger, more dangerous game.
