遙遠的地平線上：一道巨大的黑色高牆無止盡地延伸至整片景觀之中。起初看起來像是天候現象。
接著人們才發現：那道牆正在移動。緩慢地。直接朝城市而來。
一名男子開車穿過擁擠的街道，注意到恐慌正逐漸蔓延。
緊急廣播開始播放。軍用車輛飛速穿越路口。
那道牆每分鐘都變得更大：比摩天大樓還高，表面極其平滑，完全無聲，在身後吞沒陽光。
隨著它逼近：陰影不自然地拉長，氣溫下降，電子設備故障，鳥群從頭頂飛逃。
男子棄車而逃，穿過混亂的撤離人群奔跑。
在城市天際線後方：那道移動中的巨牆如今支配著整片地平線。沙塵暴盤旋著向上捲入其中。

巨牆直接高聳於市中心上方時，男子轉過身來。

Gigantic desert megacity at sunset.
Orange dust storms moving across endless highways.
People continue daily life normally.
Far on the horizon: a colossal black wall stretching infinitely across the landscape. At first it looks like weather.
Then people realize: the wall is moving. Slowly. Directly toward the city.
A man driving through crowded streets notices panic spreading gradually.
Emergency broadcasts begin. Military vehicles race through intersections. 
The wall grows larger every minute: taller than skyscrapers, perfectly smooth, completely silent,  swallowing sunlight behind it.
As it approaches: shadows stretch unnaturally, temperature drops, electronics malfunction, birds flee overhead.
The man abandons his vehicle and runs through chaotic evacuation crowds.
Behind the skyline: the giant moving wall dominates the horizon now. Dust storms spiral upward into it.
At climax: the enormous black wall reaches the outer districts of the city. The entire skyline disappears into darkness behind it.
The man turns around as the wall towers directly over downtown.
Then suddenly: the wall stops moving. Silence.
After several seconds, the structure slowly dissolves into fog and disappears.
