Gabriel returns to Smoke River, the reserve where his mother grew up and to which she returned with Gabriel's sister. The reserve is deserted after an environmental disaster killed the population, including Gabriel's family, and the wildlife. Gabriel, a brilliant scientist working for DowSanto, created GreenSweep, and indirectly led to the crisis. Now he has come to see the damage and to kill himself in the sea. But as he prepares to let the water take him, he sees a young girl in the waves. Plunging in, he saves her, and soon is saving others. Who are these people with their long black hair and almond eyes who have fallen from the sky?
