When we are first introduced to the explosive nose charge in Mission: Impossible III it is without warning. On a helicopter to safety, Ethan Hunt (Tom Cruise) attempts to save his damsel in distress (Keri Russell), but she dies seconds before he can help her. A charge, planted inside her nose, created a micro-burst that essentially imploded her brain. The result was a disgusting mess of internal debris.
The device is unbelievably fast in its action. Once triggered, it is a matter a milliseconds before death overcomes its victims. Once implanted in the nose of Hunt, it took a defibrillator to counteract the charge. It is difficult to describe just how intense the moments before death can be for a victim of this weapon.
