USA Network premiered a new show called The 4400 about a group of people (4,400 to be exact) abducted by aliens over a 60 year period. They were all returned at the same time, and they came back without aging at all -- plus many had "special" abilities that they didn't have beforehand. There is a lot more to the show, but it needs to be viewed to fully understand.
The 4400's third season begins one week from tonight -- June 11. Tonight at 10 PM Eastern, USA will air a special on the show called "Unlocking the Secrets." I'd recommend watching it if you haven't heard or seen much about the show. It could be a good place to start. USA is also airing a marathon of older epidsodes all day today.
