一个被洪水淹没的地下巨型结构，古老的石质走廊半浸在黑水中，生物发光的藻类像心跳一样沿着墙壁跳动。一名戴着面具的潜水员，身穿破旧的战术装备，手腕上的闪烁信号弹照亮了她。她被一股巨大的无眼海兽从地板格栅下方移动所产生的暗流向下拖拽，穿过正在坍塌的被淹没的密室。摄像机紧随潜水员身后，水流冲过破碎的石拱门，气泡和碎片螺旋状地掠过镜头。潜水员抓住一根断裂的柱子稳住自己，水流猛烈地撕扯着她的身体，然后她松手，自由落体般坠入一个垂直的竖井，扭动身体躲避海兽半透明的触手在黑暗中向上挥舞。快速晃动的镜头捕捉到她在坠落中点燃鱼叉枪，信号弹照亮了下方生物张开的巨大下颚。在最后的动作中，摄像机围绕着她螺旋下降，她将鱼叉射入生物的口中，生物发光体爆发出刺眼的白光，摄像机冲破一片广阔的地下海洋表面，潜水员的剪影映衬着教堂般大小的洞穴天花板上数千个跳动生物的光芒。15 秒。
A flooded underground megastructure, ancient stone corridors half-submerged in black water, bioluminescent algae pulsing like a heartbeat along the walls. A masked diver, wearing worn tactical gear, illuminated by a flickering flare on her wrist. She is dragged down by a powerful undertow generated by a massive eyeless sea beast moving beneath the floor grates, through collapsing flooded chambers. The camera follows closely behind the diver, water rushing past broken stone arches, bubbles and debris spiraling past the lens. The diver grabs a broken column to steady herself, the current tearing at her body, then she lets go, free-falling into a vertical shaft, twisting to dodge the translucent tentacles of the sea beast whipping upwards in the darkness. A fast-shaking camera captures her igniting a harpoon gun while falling, the flare illuminating the creature's massive gaping jaws below. In the final motion, the camera spirals down around her as she fires the harpoon into the creature's mouth, bioluminescence erupting into a blinding white light, the camera breaks through the surface of a vast underground ocean, the diver's silhouette silhouetted against the light of thousands of pulsing creatures on the ceiling of a cathedral-sized cavern. 15 seconds.
