Playground Poltergeist / Alien Intruder

To get the truth, sometimes you have to travel halfway around the world. That's why this week, Jael, Austin and Bill fly to the small town of Firmat, Argentina to uncover the explanation of a swing that, for four years, has appeared to be moving on its own. Ben, Chi-Lan and Devin, meanwhile, have been speaking with a Florida man, David Eckhart, and his wife, Jean, about their frequent experiences with unknowable forces. The couple say they've been visited by aliens for years, citing loss of time and mass migrations of worms in their driveway. They have two videos to back up their claims, and Ben and his team intend to discover their authenticity.
