Where Have You Been?

Susan and Ed Middleton are perfectly content with their lives.  Two kids, two cars, a solid brick bungalow in a respectable northern beaches suburb.  They're good people, model citizens.  There's barely a ripple in the surface of their happy existence.  But when Susan's older sister, who vanished as a teenager, reappears to claim an inheritance, everything is set to change...

Karen - now known as Carly - has had a tough time during the past twenty years: drugs, prostitution, prison.  At least that's what she tells them.  As Carly insinuates herself further and further into the Middleton's lives, suspicions are aroused - is she really Susan's sister, returned from the dead?  If she isn't Karen, who is she?
