PAqnPEQiOpE 4:43–5:46 — They're right by the water, but screened from public view by the trees.
PAqnPEQiOpE 5:52–7:04 — They may be in southern Finland, but they're still close enough to the Arctic Circle that the sun never fully sets in the summer.
PAqnPEQiOpE 7:07–8:08 — A local man, Esko Johansson, arrives with his two sons. They take in the stunning scene before them.

PAqnPEQiOpE 9:21–10:35 — Each of the teenagers have been stabbed and bludgeoned. They all have broken jaws and severely fractured skulls.

字幕依据：They're right by the water, but screened from public view by the trees. They lean their two motorcycles against nearby trees and pitch a small tent that's just big enough to fit them all inside. Maila keeps thinking back to the woman who sold them their drinks, the look she gave to the four of them. PAqnPEQiOpE@4:43
字幕依据：They may be in southern Finland, but they're still close enough to the Arctic Circle that the sun never fully sets in the summer. It dips low until it's barely touching the horizon and stays there. And as night falls, the sky dims to a sort of warm twilight, a phenomenon known as a midnight sun. PAqnPEQiOpE@5:52
字幕依据：A local man, Esko Johansson, arrives with his two sons. They take in the stunning scene before them. If today's going to be anything like yesterday, it'll be perfect weather for swimming. They make a brisk walk towards the lake shore eager to plunge into the refreshing water. PAqnPEQiOpE@7:07
字幕依据：NARRATOR: This program is about unsolved mysteries. Whenever possible, the actual family members and police officials have participated in recreating the events. What you are about to see is not a news broadcast. Tonight, a special "Unsolved Mysteries" report-- "Mysteries of Alien Beings." Who are they? dM2DFl1FJps@0:05
字幕依据：And while I'm trying to figure this out, I notice this dark, shadowy type figure emerging from this bright light in front of me. It wasn't like other nightmares, where you have some strange dumb dream or something, and you forget about it the next day. dM2DFl1FJps@1:18
字幕依据：For almost 50 years, the so-called Roswell incident has fascinated and confounded UFO researchers. Tonight, in an exclusive update, a new eyewitness account suggests that the army did, in fact, recover the bodies of alien beings in 1947. dM2DFl1FJps@2:28
字幕依据：In the most dramatic episodes, an entire community will report seeing the same object in the sky for weeks, months, or even years. That is exactly what happened over New York's Hudson Valley between 1983 and 1986. Perhaps no account was more convincing than that of Ed Burns, a computer engineer. dM2DFl1FJps@4:52
字幕依据：It first appeared in 1947, when a pilot named Kenneth Arnold claimed that he encountered not one, but nine mysterious flying objects out on a search and rescue mission over Washington state. When a headline writer tried to describe what Arnold saw, he coined the phrase "flying saucer" and helped launch the modern era of UFOs. dM2DFl1FJps@6:02
