Premise: This classy sci-fi hit revolves around the sudden reappearance of 4400 missing people. All were presumed dead or reported missing over several decades, and many return to their former lives on Earth---but with startling powers. Among those assigned to unravel their mystery is an earnest crime investigator whose nephew is one of the returned. The cable drama, originally slated to run only as a five-part miniseries, garnered big ratings for USA and was added to its regular roster.
