Video reveals how man survived 3 days underwater

Harrison Okene survived for three days, without food or water, after his tugboat capsized off the coast of Nigeria six months ago.

Now, video has surfaced of his dramatic underwater rescue at sea. The video shows how he was able to breathe, nearly 100 feet under the surface, thanks to an air pocket in the wreckage. His 11 crewmates died.

Okene said after his rescue, "I was there in total darkness, just thinking it's the end."
