Editing Trick of the Dark

Today i got quite a surprise as i was brought into a meeting with my lectures to ask if i had the time to edit another film as the original editor could not manage both films she was on. I said yes to this as not only was it the film i had originally wanted to edit, but i also love a challenge, and boy was this a challenge, we where two weeks before deadline they had only filmed about 1/3 of the original script. and do not have enough to get across the story they are hoping for. The film it self is suppose to follow three people trapped in a cave, two males and one female, with the ocational other male that brings them supplies, but the twist of this film(cause all films need to have a twist) is that the end scene sees one of the people in the cave wake up in the hospital confused, he then looks at the TV to see both of the other people that where trapped in the cave presenting a children's show. I think from what i can remember it is suppose to be that he has had a failed suicide attempt and his imagination has made up the hole cave stuff using things around him, this is especially implied when you see that the guy that was helping then with supplies i the cave turns out to be the doctor. I am very excited to get a look at what thy have shot of this film to see what i can do with it, i will probably not use what has already been edited, by the previous editor as i like to start from scratch to that i can get a good idea of what the story is suppose to be.
