The hit series for the USA Network, The 4400, enters its 4th season starting Sunday, July 17th. A quick synopsis: THE 4400 follows 4,400 people who are abducted, taken away and then returned to planet Earth. After their return, many of them discover they have superpowers. As the fourth season begins on June 17, the plot follows the development of a drug called Promicin and its ability to give its users superpowers, if it doesn’t kill them first. Three different factions have emerged around the drug: pro, anti- and neutral.. Several web sites have been set up about the drug – check out www.promicininfo.com, www.promicinterror.com and www.promicinpower.com.
