In the infinitesimal world of subatomic particles, a danger exists that few know about. A Higgs boson, also known as the "God particle," through reaching its true energy state, could lead to the redefining of the universe. When the Proctor family discovers that such an event, located three light-years away, is soon to take place, they are called on once again to save all humanity. Beta Mortenson, a Nobel Prize-winning physicist and prime member of the Proctor family, is tasked with the overwhelming responsibility for stopping the total annihilation of all matter in the cosmos. Gamma Proctor, a ten-year-old little girl who saved Earth from a gamma-ray burst by sacrificing her life, now existing in another dimension, can no longer guide the Proctor family to the quantum world. However, still able to communicate with Beta, she trains the brilliant physicist on how to lead her movie star husband and Dr. John Tate back to the subatomic realm where once again the world's fate will be decided. When Beta fails to make progress, Gamma, her celestial guide, suggests that they locate a young friend from their past who is currently homeless and living on the streets of London. Only with the help of eighteen-year-old Briana Boyer can the Proctor family hope to prevail.
