Reckless and irresponsible young man falls and becomes trapped in a crevice, after having told no one where he went.
Since there is not much of a plot, in order to attempt to gain interest, the movie resorts to flashbacks and clever camera tricks to show basic action, e.g. slow motion view inside the water bottle as he drinks.
I found the movie rather boring, and the character uninspiring, despite the good performance by James Franco.
