In 2048, humanity's survival is on the line. After a superstorm nearly destroys them, teenagers Jimmy and Lizzie Marshall push their nanoscientist dad, Greg, to unleash WhiteGrass, a groundbreaking nanotech to fight climate change. With his AI expert wife, Ginny, they reprogram the world's most advanced humanoid, Valada, to help. But a powerful syndicate of oligarchs sets its sights on WhiteGrass.

The Marshalls' mission takes on a dark turn when shadowy power brokers, led by the President of the United States herself, will stop at nothing-covert theft, blackmail, even violence-to control the technology that could save or subjugate nations. They deploy their own deadly android to seize the prize.

The family must fight to save the technology but, most importantly, each other.
