The whole movie is set in a box that this guy is buried in. He has a cell phone which he can use and a few other things. It is pretty tense for a movie set in a box. But the story goes no where. He manages to call someone who says they are going to rescue him. WRONG BOX, HE DROWNS IN SAND FILLING UP HIS BOX. MOVIE FINISHES, I FEEL DEPRESSED FOR NEXT 2 DAYS... THIS IS MY REVENGE.
