Ultra-wide aerial begins miles above snowy peaks, then plunges into a fast dive toward a train entering a mountain pass. An avalanche breaks loose and pours down behind the train, filling the valley with a moving white wall. Camera skims along the ridgeline parallel to the tracks, then swings into a wide arc that keeps both the train and avalanche visible as the train races toward a tunnel. End with a rapid climb revealing the avalanche swallowing the pass behind the tunnel mouth.
超广角航拍镜头从数英里高的雪峰之上开始，随即急速俯冲向一列正驶入山口的火车。一场雪崩崩塌并在火车后方倾泻而下，用一道移动的白墙填满山谷。摄像机沿着与铁轨平行的山脊线掠过，随后摆动成一个宽阔的弧线，在火车冲向隧道的同时，让火车和雪崩都保持在画面中。最后以快速爬升结束，展示雪崩正在吞噬隧道口后方的山口。
