Circumstance Escape

You had spent some days on the island that is close to your home city. It was during the vacation trip with your family. You kept telling so many good things about the island to your friends who now wanted to go to the island and they wanted you to be their guide during the trip. All plans were made and finally the decided date came and you all boarded a plane to fly away to the island but unfortunately it has crash landed in a forest. Later when you open your eyes you find no one around. Not sure who else other than you have survived but you start looking for a way to signal to the authorities and hopefully find other survivors.
