Julaine plane crashes, due to the striking of lighting causing the plane's Lockheed Electra to fail. Juliane fell out the crashing plane still strapped on to her seat and wasn't severely hurt. She then spent the night trying to keep out of the rain using her seat.
The Central idea is how one can be able to survive in a life or death situation, and also, that you should always be mentally prepared. Also, another event that'd happen is Juliane did not wait for rescuers to come find her, she knew she had to make a plan and take responsibility into her own hands. So she then made her way downhill to hopefully find a river.
While the other survivors waited for rescuers to come, Juliane made her way downhill hoping for a chance to survive in the jungle. With bugs biting her and worms crawling in her skin she managed to get saved by a nearby civilization being saved and one of the very few to survive.
