An exclusive video shows five kids' plight to escape a sewer system. The five friends were exploring the sewers in Staten Island, New York, with only the light of a cellphone guiding them. All of a sudden, they lost their way. Amazingly, the sixth graders finally received a cellphone signal and called 911. An operator tried to lead rescuers to their location. As the kids started to scream, rescuers were able to find them.
