Grace and Harris must forge an alliance when their children's lives are in jeopardy. Also, Liam presents Jillian with an unusual proposal.
An MIT grad student and a tech superstar bring a low-level Pentagon official a staggering discovery that an asteroid is just six months away from colliding with Earth. Without alerting the public, MIT grad student Liam Cole and tech billionaire Darius Tanz team up to save humanity from this impending apocalypse. Keeping it secret will complicate life for Liam and those closest to him.
Meanwhile, the government has its own approach. Grace Barrows is both the Pentagon Press Secretary and a single mom, and she deftly navigates the complicated waters of both jobs. Deputy Secretary of Defense Harris Edwards has been tasked with running their own top-secret plan to deflect the asteroid. Meanwhile, Darius recruits an aspiring sci-fi writer, Jillian, to work on a theoretical approach to saving humanity - a project that might prove to be all too real.
