In the series premiere, Emma, a kind-hearted foster kid, has recently discovered she has an identical twin sister, Sutton. Unlike Emma, who has bounced from foster home to foster home, Sutton was adopted by wealthy parents, Ted (series star ANDY BUCKLEY) and Kristin Mercer (series star HELEN SLATER), and is seemingly living every teenager's dream life.

Emma and Sutton agree to continue their separate lives - but when Emma has an unfortunate encounter with her foster family and is forced to flee, the only person she can turn to is Sutton.
