General.

It isn't paranoia if it's really happening... Anna Fox lives alone -- a recluse in her New York City home, drinking too much wine, watching old movies... and spying on her neighbors. Then the Russells move next door: a father, a mother, their teenaged son. The perfect family. But when Anna sees something she shouldn't, her world begins to crumble -- and its shocking secrets are laid bare. What is real? What is imagined? Who is in danger? Who is in control? In this gripping Hitchcockian thriller, no one and nothing are what they seem.
