What if one of the most famous and terrifying urban legends was not a legend but a frightening fact? History tells us that Alligators lurking around in the sewers of New York City is 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, Teddy May, was forced to investigate for himself. What May 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. Experts, however, are divided over whether it is scientifically possible for alligators to continue to exist in the sewers, so a MonsterQuest team sets out to search for modern evidence of these monsters and prove that they could not only survive but also thrive.
