Built underground, something dug and found the egg-shaped spaceship (?) Forms, steel gray-blue color, it seems. And all this was obviously in some kind of a building under roof and the action takes place in this building. I remember when they tried to drill diamond drill bit, but nothing happened. Then came some kind of hell, and all either dead, or missing. Themselves aliens, or who could sit in there, it seems, and not shown. Looked about 15 years ago.
