In the dark trunk of a moving car, Sam awakes. She doesn't know how she got there, where she's being taken, or who she even is. The only thing she knows is she has to get away. With a superhuman strength that surprises her, she overpowers her captors and escapes into the nearby woods, taking refuge in a lean-to under cover of night. When morning dawns, she finds she's no longer alone-a rancher has discovered her, and she's trespassing on his property. With nowhere else to turn, she follows him back to his farmhouse, where she's welcomed by his right-hand man, Mack, and his housekeeper, Miss Claire. As Staz and his crew work to help Sam uncover her identity, she begins to understand that she wields powers no human being, let alone a teenage girl, should have. Then they uncover links to GNT, a shady, billion-dollar bioengineering company. All the while, Sam grows closer to the handsome, mysterious Staz, who may be hiding secrets of his own. But the more Sam learns, the more the truth eludes her.
