When the body of a young man is found in a beachfront apartment in Bondi, Detectives Tori Lustigman and Nick Manning are assigned the case. Is this brutal murder a domestic, a robbery gone wrong or something far more sinister?

As other ritualistic murders occur, they discover the killer is using a social networking app to entice his victims. Anyone using the app is now at risk, and it's a race against the clock to catch the serial killer before he strikes again.

With mounting evidence to suggest the perpetrator has killed before, Tori and Nick start digging through old investigations. The discovery is shocking. They uncover up to 80 possible murders of men that took place in the 80s and 90s in NSW - unexplained deaths, ‘suicides' and disappearances. Haunted by the disappearance of her teenage brother, Tori's fascination with the case soon turns to fixation.

As they investigate past crimes, they become convinced that the current killer is somehow connected. In reopening the cold cases the detectives reveal the hidden truth about the past murders and uncover critical evidence leading to the killer. In doing so they finally give closure to the victims' families bybringing the killers, both past and present, to justice.

Deep Water - Deep sea - Netflix

The deep sea or deep layer is the lowest layer in the ocean, existing below the thermocline and above the seabed, at a depth of 1000 fathoms (1800 m) or more. Little or no light penetrates this part of the ocean, and most of the organisms that live there rely for subsistence on falling organic matter produced in the photic zone. For this reason, scientists once assumed that life would be sparse in the deep ocean, but virtually every probe has revealed that, on the contrary, life is abundant in the deep ocean.

From the time of Pliny until the late nineteenth century...humans believed there was no life in the deep. It took a historic expedition in the ship Challenger between 1872 and 1876 to prove Pliny wrong; its deep-sea dredges and trawls brought up living things from all depths that could be reached. Yet even in the twentieth century scientists continued to imagine that life at great depth was insubstantial, or somehow inconsequential. The eternal dark, the almost inconceivable pressure, and the extreme cold that exist below one thousand meters were, they thought, so forbidding as to have all but extinguished life. The reverse is in fact true....(Below 200 meters) lies the largest habitat on earth.

In 1960, the Bathyscaphe Trieste descended to the bottom of the Mariana Trench near Guam, at 10,911 m (35,797 ft; 6.780 mi), the deepest known spot in any ocean. If Mount Everest (8,848 metres) were submerged there, its peak would be more than a mile beneath the surface. The Trieste was retired, and for a while the Japanese remote-operated vehicle (ROV) Kaikō was the only vessel capable of reaching this depth. It was lost at sea in 2003. In May and June 2009, the hybrid-ROV (HROV) Nereus returned to the Challenger Deep for a series of three dives to depths exceeding 10,900 meters. It has been suggested that more is known about the Moon than the deepest parts of the ocean. Little was known about the extent of life on the deep ocean floor until the discovery of thriving colonies of shrimps and other organisms around hydrothermal vents in the late 1970s. Before the discovery of the undersea vents, it had been accepted that almost all life on earth obtained its energy (one way or another) from the sun. The new discoveries revealed groups of creatures that obtained nutrients and energy directly from thermal sources and chemical reactions associated with changes to mineral deposits. These organisms thrive in completely lightless and anaerobic environments in highly saline water that may reach 300 °F (150 °C), drawing their sustenance from hydrogen sulfide, which is highly toxic to almost all terrestrial life. The revolutionary discovery that life can exist under these extreme conditions changed opinions about the chances of there being life elsewhere in the universe. Scientists now speculate that Europa, one of Jupiter's moons, may be able to support life beneath its icy surface, where there is evidence of a global ocean of liquid water.

Deep Water - Salinity - Netflix

Salinity is remarkably constant throughout the deep sea, at about 35 parts per thousand. There are some minor differences in salinity, but none that is ecologically significant, except in the Mediterranean and Red Seas.
