It's a good movie that will be convenient for both those who like war movies and those who like horror movies. The story line is that Dr. Clyne is the one who invented military cameras...One day, soldiers were killed by an unknown object and could only see it with the camera developed by Dr. Clyne, so Dr. Clyne was called back and examined by the military organization And those things are human It has a form and can pass through walls like spirits, and anyone who touches it freezes to death. It cannot be raised by any weapon. Are these things evil or are they military secrets?
