They are soon surrounded by great white sharks, but the winch boom breaks free and the cage sinks to the ocean floor, 47 m (154 ft) below the surface and out of communication range with the boat.

Both women are running out of air but soon see a flashlight in the distance and Lisa swims out to attract attention, managing to avoid a shark which tries to attack her.

It is then revealed that Lisa has been hallucinating due to nitrogen narcosis and that she is still at the bottom of the ocean with her leg pinned under the cage, with Kate gone.

As Coast Guard divers arrive to rescue her, she begins coming out of her hallucination, calling out for Kate, who she realizes was killed earlier by the great white shark.

Original distributor Dimension Films had initially set a North American DVD and VOD release date for 2 August 2016.

However, several retailers broke the street date, and a handful of physical copies were sold and have since turned up on eBay as collectors' items.

[3] In North America, 47 Meters Down was released alongside All Eyez on Me, Rough Night and Cars 3 and was initially projected to gross around $5 million from 2,300 theatres in its opening weekend.

The website's critical consensus reads, "47 Meters Down doesn't take its terrifying premise quite as far as it should, but its toothy antagonists still offer a few thrills for less demanding genre enthusiasts.

[10] Joe Leydon of Variety wrote: "Director Johannes Roberts' mostly underwater thriller is a compact and sturdily crafted B-movie that generates enough scares and suspense to qualify as — well, maybe not a pleasant surprise, but a reasonably entertaining one.

[17] On 8 September 2017, it was announced that production studio, The Fyzz Facility, is working on a sequel titled 48 Meters Down, in which Roberts, Riera, and Harris & Lane will return as director/writer, co-writer, and producers, respectively.

[18] The sequel is set in Mexico and centers around a group of young women who decide to explore some hidden underwater ruins located off-the-beaten trail.

The new cast members are John Corbett, Nia Long, Sophie Nelisse, Corinne Foxx, Sistine Stallone, Brianne Tju, Davi Santos, Khylin Rhambo and Brec Bassinger.
