One hundred feet under the sea, a shadowy hand reaches out of the pitch black and grabs at your arm.
No, it's not a horror story.
It's the incredible, true tale of the rescue of Harrison Okene, a chef for an oil company who survived three days trapped at the bottom of the sea after his boat capsized off the coast of Nigeria in May.
Now a video has been released showing Harrison trapped in a small air pocket that formed when the ship sank. (Check out the video below.)
He had no food or fresh water but, according to the BBC, survived with just one bottle of Coca Cola.
Expecting to find only bodies in the wreckage, recovery divers from the DNC diving company quickly turned the mission into a rescue operation when Harrison reached out from the darkness.
Divers used warm water to increase his body temperature, fitted Harrison with a scuba mask, and brought him to a decompression chamber, where he spent another 60 hours readjusting before safely surfacing. He was the only survivor of the 12 member crew.
Harrison is now at home in Nigeria, with his family.
