兩名身穿戰術服的特工沿著摩天大樓緊急樓梯向下狂奔，腳下平台崩塌，保全從上方逼近

提示詞

夜晚。在一棟極高的現代摩天大樓緊急樓梯間內，兩名特工，一男一女，正飛快往下逃跑，一支保全隊伍則從上方追趕。樓梯間由混凝土和金屬構成，設有紅色緊急照明、煙霧、閃爍的警報燈、外露管線、鋼製扶手，狹窄的窗戶外可見城市燈火。兩名特工都穿著深色合身的戰術服裝，不戴兜帽、頭盔或面罩，頭髮清晰可見，外貌不仿任何名人。

開場廣角鏡頭：特工們飛奔下樓，快速跨下階梯，並利用扶手保持平衡。保全隊伍出現在上方數層樓處，逐漸逼近。

快速跟拍鏡頭：樓梯間劇烈震動。下方的平台開始出現蔓延的裂縫。灰塵從天花板落下。金屬扶手嘎嘎作響，特工們迅速反應，繼續往下移動。

側面鏡頭：下方一段平台突然斷裂脫落，在樓梯段之間形成缺口。特工們沒有停下。他們抓住扶手，繞過斷裂處擺盪而過，再跳落到下一個穩固的平台。

最後 5 秒：動作更加激烈。下方更多樓梯段出現裂縫。特工們飛奔下另一段樓梯，一根金屬支撐梁彎折，下方的平台隨之崩塌脫落。一名特工踩到灰塵滑倒，另一名特工及時接住他們，兩人迅速而穩定地跳落到更低處的樓梯段，重重著地後繼續往下跑。

最後一刻：特工們抵達下方的緊急出口，推門衝出；他們身後的樓梯間劇烈震動，灰塵與紅色警報燈光充滿畫面。

風格：超寫實、電影感、節奏快速、緊張、急迫、動作清晰易辨，強烈的垂直墜落危險感，崩塌中的樓梯間，紅色緊急照明、煙霧、灰塵、金屬扶手，鏡頭運動動感但清晰，無文字、無標誌、無卡通風格、無慢動作。保持比例。保持風格與特徵。畫面比例 16:9。

Night. Inside the emergency stairwell of a very tall modern skyscraper, two agents, one man and one woman, race downward while a security team follows above them. The stairwell is concrete and metal, with red emergency lights, smoke haze, flashing alarms, exposed pipes, steel railings, and city lights visible through narrow windows. Both agents wear dark fitted tactical clothing, no hoods, no helmets, no masks, visible hair, no celebrity resemblance.

Wide opening shot: the agents rush down the stairwell, taking the steps fast, using the railings for balance. Security appears several floors above, closing in.

Fast tracking shot: the stairwell shakes. Cracks spread across a landing below them. Dust falls from the ceiling. The agents react quickly and keep moving downward as the metal railings rattle.

Side shot: a landing section suddenly breaks loose below them, creating a gap between stair sections. The agents do not stop. They grab the railing, swing around the broken area, and drop down to the next stable landing.

Final 5 seconds: the action becomes more intense. More stair sections crack below them. The agents sprint down another flight as a metal support beam bends and a lower landing collapses away. One agent slips on dust, the other catches them, and both make a fast controlled drop to a lower stair section, landing hard and continuing downward.

Final moment: the agents reach a lower emergency door and push through it as the stairwell behind them shakes, dust and red alarm light filling the frame.

Style: hyper-realistic, cinematic, fast-paced, tense, urgent, clean and readable action, strong vertical danger, collapsing stairwell, red emergency lights, smoke haze, dust, metal railings, dynamic but clear camera movement, no text, no logos, no cartoon style, no slow motion. Keep proportions. Keep style and features. Aspect ratio 16:9.
