Lombardo and Dundee could hardly be classified as shrinking violets themselves. The crews that worked for Unbelievable Mysteries had to be physically fit, aggressive in pursuing a story and preferably brain-dead. The cable TV series had a high turnover and injury rate. With its emphasis on high-risk adventures, the series was tough on production crews - in fact, the misadventures of the crews, rather than their main assignments, often became the topic of each episode. It was the logical continuation of the “true-life” adventure inspired by the success of the Survivor series and its clones. If a reporter or technician were swept into the sea or pursued by cannibals, it made for a better story. As long as a crew didn't lose expensive equipment, management didn't care how hazardous working conditions were.

They had arrived in Istanbul a few days earlier to launch a search for Noah's ark. The ark was an overworked cliché that even the supermarket tabloids had consigned to the back section with Elvis sightings and the Loch Ness monster, so Kaela had kept a sharp eye out for other leads in case the ark story didn't pan out. Their first day, while Kaela was looking for a fishing boat to take them into the Black Sea, she'd struck up a conversation with a colorful old Russian seaman she met on the docks. He had served on a Soviet missile sub and told her about an abandoned submarine base, even drew her a map showing the base's location in a remote comer of the Black Sea, after hinting that a gift of money might refresh his failing memory.

When Kaela approached her colleagues and excitedly poured out the story of the abandoned Soviet submarine base, they lost no time planning a side trip. The sub base might make a good backup if the search for Noah's ark fell apart, as it probably would. The fishing boat had been hired to take them to a rendezvous with a research vessel from the National Underwater and Marine Agency.

Captain Kemal, the boat's owner, was paid by the day, and said he knew of the sub base and would be happy to go there before they hooked up with the NUMA vessel. However, the fishing boat had engine trouble as they neared the base and the captain wanted to turn back to port - he'd had a similar problem before and it would take only a few hours to fix it once he had the part - but Kaela had persuaded him to drop her and her crew off and come back for them the next day. Mehmet, who was the captain's cousin, had volunteered to run them ashore in his Zodiac.
