This guy goes into a silo type building from an entrance in the ground.
He meets with someone and there is computers in the room.
He ends up doing something with electronics.
I think a missile gets fired and he comes out of the silo.
This is vague but all my mind can conjure.
Funny thing is that I have the movie but can't find it,
Thousands of titles to go through doesn't sound much fun on IMDB!
Thanks for any help
