How long can you keep hard boiled eggs?

The film begins as an apparently straightforward film about the bond between a cop and an undercover cop as they fight a triad gang. However, it develops into an over two hour action extravaganza, with a body count of 307. It is structured around three major action setpieces: the opening teahouse shootout, the warehouse betrayal in the middle and the climactic thirty-minute hospital shootout.
