Seasoned deep-sea divers battle the raging elements to rescue their crewmate trapped hundreds of feet below the ocean's surface.

OceanGate's Titan tourist submersible imploded in 2023 on a deep-sea dive to the Titanic. This documentary details how a bold vision ended in tragedy.

In the deep ocean, life is concentrated at chemosynthetic oases where primary production is made possible via chemosynthesis at cold seeps and deep sea hydrothermal vents. The non-chemosynthetic regions of the deep are divided into two very different worlds. The worlds of the deep sea could not be more different, and yet their stories are fundamentally intertwined. In this movie, we delve into the Twilight Zone.

In the deep ocean, life is divided between very different worlds inhabited by weird and wonderful deep sea creatures. In the midwater, pelagic wanderers tread migratory routes that span entire oceans, and planktonic drifters and their predators take part in bioluminescent light shows. It is separated into zones based on depth, including the sunlight zone (epipelagic), twilight zone (mesopelagic), midnight zone (bathypelagic), abyssal and hadal zones. And below, lies the deep sea floor. A kingdom of mud and ooze, where sessile creatures cling to any solid outcrop and corals craft kingdoms on the seamount crusts. The worlds of the deep sea could not be more different, and yet their stories are fundamentally intertwined. In this film, we delve into the Midnight Zone and the Twilight Zone, where anglerfish, giant sharks, and bioluminescent wonders are found traversing the void. Join as we uncover fascinating deep ocean facts and mysteries.

In this episode, we delve into the Midnight Zone, a pitch-black zone of the deep sea where life has found peculiar ways to survive the immense pressure, from anglerfish to vampire squid to giant sharks.
