This is my twisted idea of an alternate ending to the movie Buried, where an American civilian truck driver is captured, and buried alive, and used for a ransom that never comes.
As the sand continued to pour in, rising to his face, Paul gave up all hope of rescue. Dan Brenner's last words "I'm sorry, Paul. I'm sorry." were ringing in his ears. "They never rescued Mark White. Hell, they probably never rescued any of them."
The sand finally poured in, covering his face and noce, and as he lay there suffocating, thrashing about in panic, he thought: Goodbye, Linda. But his foot, thrashing about with the strength of death throes, broke through a coffin wall, causing the sand to start pouring out through it, and light, very faint but there nonetheless, poured in. Not that he could see it yet. He did however feel his foot go through something, and used his hands to rapidly push sand to the end of the coffin, freeing up air to breath. "I'm alive? I'm alive!"
He then continued to push sand down until he could see the light, and started kicking the weakened coffin wall until there was a hole big enough to stick his feet into. He started shimmying through it, until, finally, he fell a few feet down, landing in a dim room.
Pal looked around, and saw that in the room was an oven/stove top mix, the burners on, glowing a faint orange, a tube tv, and a desert hat, hanging from the ceiling by a copper wire. "What the hell is this? What is this place?"
He looked behind him, and saw a steel hatch in the wall, with metal bars going into concrete on one side, with gears in the hatch. Seeing no other way out, he walked over to the hatch, and tried frantically to open it. After ten seconds or so of this, the tv turns on, and the noise alerts Paul, who turns to see a person in a clown mask on it.
"Hello, Paul. I want to play a game."
