After reviewing the week's finds, Devin goes with Ben and Jael to attempt to unearth the truth behind a famous photo taken by an LA Times photographer in 1942, just after the Pearl Harbor attack and five years before the Roswell incident, of an object flying through the night sky.

Chi-Lan, Bill and Austin, meanwhile, investigate the Queen Mary Ghost in Long Beach, where the famous ship has been moored since the '60s.

One of the hottest cases this week comes from Jacksonville, Florida, from the historic Florida Theatre. Bill, Austin and Chi-Lan head to this reported hotbed of paranormal activity to get to the bottom of an amazing video: A local expert, Steve Christian, was conducting a paranormal investigation in the theater when he caught, on camera, a figure seated in the balcony - waving.

Ben, Devin and Jael, meanwhile, have also been down south, searching for the truth behind a reported UFO sighting. What's special about this one is that there's video of a flare descending toward Earth, splitting into three lights, and then hovering for a period.

Ben, Jael and Austin head to Long Beach, CA, where the video of an unidentified object flying over the harbor, seeming to drop glowing seeds into the water, was recorded.

Chi-Lan, Bill and Devin, meanwhile, have been digging into a decades-old mystery of a Winnipeg man who claimed to have captured ectoplasm - a ghostly substance said to be produced by a medium during a séance - on camera at the turn of the last century.

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.

Ben, Chi-Lan and Devin head to Texas on a hunt for the blood-sucking cryptid known as the chupacabra. The local sherrif saw a strange, unidentifiable animal running down a country road, and murmurs of the chupacabra swelled up around the video she shot from her vehicle.

Jael, Austin and Bill, meanwhile, are looking into what seems to be an alien walking plainly through a shot from a local news segment in Patagonia, Argentina, where UFO and alien sightings are frequent.
