A comet from another solar system.
A conspiracy at the highest levels.
A family caught between the truth,
And the end of the world.

Inside NASA, scientists whisper the unthinkable: What if this isn’t natural?

Black Swan reveals a conspiracy that threatens the world but will leave you asking,

“Are we alone?”
