MonsterQuest (2007)

Season 3: Episode 5

History tells us that tales of Alligators lurking around in the sewers of New York are based in truth. In the mid 1930s three teenagers pulled an eight-foot alligator from a storm drain. Reports persisted until a skeptical Superintendant of Sewers was forced to investigate for himself. What was found shocked even him - swarms of alligators alive beneath the busy main street of America's biggest city. Crews were sent in to kill the deadly reptiles, but the stories of the gators in the sewers lived on to this day.
