Elly is a botanist who does some research in search of a flower that, as she will explain later, should not have survived in this desert environment. On the way home, she notices a small plane crashing in the desert. Terrified, she hurries to the scene to offer help, and there she finds the pilot, a man named Tomas, who is seriously injured but still alive. It is surrounded by two white bricks that are obviously drugs. He threatens Elly with a gun, and she tells him she can drive him to California.
