Mission: Impossible - Dead Reckoning Part One
Summary

The film opens with the Russian submarine Sevastopol deep in the ocean carrying a potentially devastating computer gadget. A special key shaped like a cross that has been cut in half is used to unlock the device. The submarine's crew spots what they believe to be an enemy vessel firing a torpedo in their direction. They return fire with their own torpedoes, only to be taken aback when they see that the enemy submarine and their own projectiles have vanished into thin air. The submarine and its whole crew are wiped out as the crew's torpedo is reflected to them.
