When MIT grad student Liam Cole discovers an asteroid is set to collide with Earth in 186 days, he joins forces with tech billionaire Darius Tanz and the U.S. government to try and stop it – and together they stumble onto the greatest conspiracy never told.
Darius and Liam work to invent a theoretically impossible piece of technology to divert the asteroid. Also, Liam heads home to Boston to track down critical research but finds something shocking instead.
It's a race against time as Darius must accelerate his plan to stop the asteroid before the Pentagon shuts him down. Also, Grace has to make difficult decisions that could have life or death consequences for millions of people, and Liam and Jillian reunite under surprising circumstances.
After a nuclear incident, the secret of the asteroid becomes public, setting the world on a dangerous course. Darius, Grace, Liam and Harris must adapt to new roles in an ever-shifting landscape of fear and civil unrest.
