Lily needs a ride—a fire warning in Oregon has cancelled her train home to California. Her ex-best friend, Natasha, has offered to pick Lily up on her way back from Portland, though they're barely on speaking terms. As it turns out, Natasha's also giving a ride to Elke Azizi, the girl Lily got expelled from their school 4 years ago. There's smoke in the air, and with the wildfires nearby, staying on the road is becoming riskier by the hour. When Natasha and Elke decide to take a detour, Lily hopes it'll get them out of danger. But as night comes, the plans change again when it becomes all too clear that leaving the main road was a mistake. Now the 3 of them are trapped in the woods under a burning sky, with no easy way out. To survive, Lily must depend on Elke and Natasha—but after all that's happened, can she trust them with her life?
