They're here to save the world.

After losing their university jobs, three parapsychologists start a ghost-catching business in New York City and uncover a supernatural threat that could destroy the world.
In Ghostbusters, consciousness is carried by the dead — a plane of “paranormal city”. The story fights on E8/E11 of the E0–E14 reality ladder, compressing technology, fear, authority, otherness.
Films fighting at the same level of reality, about the same things.
The same preoccupations examined at another scale — one mind versus a nation.
