After Brian finds out that his mom was secretly dating another man, his parents get a divorce.  While flying to his dad’s house to spend the summer the pilot has a heart attack and dies.  Brian the decides to crash land the plane in a pond, after he swims up somehow surviving the crash, he find that his head is badly bruised and his muscles tight.  He sleeps till morning, but the morning brings mobs of mosquitoes and flies.

If I was in the situation that Brian is in I would, hunt for food with the hatchet which I think is still attached to his belt.  Then I would seek out sticks in the woodland that surrounds me, and start a fire.  The fire would be a beacon to alert people of my location, as well as heating me up.  The smoke it sets off would also keep the mosquitoes and flies away, protecting me from future attacks.
