They're here---aliens, that is, surfacing in a Florida hurricane and assuming human form. But the ETs may have been there long before. That's the setup for this provocatively cryptic sci-fi mystery, which is eerily reminiscent of the classic `Invasion of the Body Snatchers' as well as 'The X-Files.' The drama was created by Shaun Cassidy (`American Gothic'), who describes the series as mixing `darkness and light. It's all about the balance.'
