Aliens attack Earth, or so world governments believe. In the aftermath of global warfare brought on by the crash of an alien spacecraft, Adriana wakes up in a hospital-like facility with no memory of who she is or how she got there. The administrator tells her she has family on the outside that she needs to find. When she leaves, she begins to hear whispers in her mind that draw her to a disparate group of strangers that she instinctively feels are her brothers and sisters. After discovering that they all share an astonishing connection to the alien arrivals, Adriana resolves to protect her family members from a sinister organization intent on tracking down and annihilating them.
