I am looking for an old movie I saw when I was young. I think it might have been an after school special called Exiled. It was about a group of high school kids going on a trip. Their plane crashed on an island and they were stranded. They had to learn how to survive and get along with each other. I remember one scene where two of the kids were hanging out in a cove in the water and the tide was coming in. The boys' foot got stuck under a rock and his girlfriend went to get help, but by the time she came back he had drowned. Anyone remember this film?

Well off the top of my head I was going to say "lord of the flies", but there was no girls in it..
The discription sounds fimilair so I will do some searching..

Here is something else...

Flight 29 Down - Wikipedia, the free encyclopedia

Close its called Exile. Great Corey Feldman movie.
