In short it is a relatively stupid show about 4400 people who over the last century have been abducted by aliens and were all returned to Earth at the same time. Also, all are exactly the same age as they were when abducted and have no memory of the time lapse while they were gone. Many of those returned have special powers such as healing or being able to tell the future... Supposedly they were abducted by humans in our future and returned so that they can keep the human race from doing ourselves in. Like I said, pretty silly but nothing else is on TV Sunday night. We watched it last year and this year but with them now turning out to be nothing but a Feinswine mouthpiece, screw the show. I'll watch the National Geographic channel (not that they are any friend to gun owners).
