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. Both girls are eager to meet each other in person, yet Sutton feels it is better to wait until she tells her adoptive parents what she has discovered. 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.

A body is found in the woods mauled by a bear and Walt suspects that the bear was baited to attack. He and the team must track down both the bear and the person who used it as a murder weapon. When they discover that the victim was a murderer released early from prison due to overcrowding, it leads to a long list of suspects. Meanwhile, Walt must deal with Branch's uncle Lucian (guest star Peter Weller), a former sheriff who is brought into custody after firing a shotgun in his retirement home and who can't resist inserting himself into the investigation.

Don and Ruth Ferguson are two of the nicest people you'll ever meet. They're devoted to the Catholic Church, they spend all of their time working at a homeless shelter and they've managed to recreate their lives after leaving everything behind to enter the Witness Protection Program. The only problem is: they can't stand each other, and they're too Catholic to divorce. Despite their misery, Ruth is devastated when she hears that Don has died in a traffic accident. As Mary investigates, she learns that the case is more complicated than it seems at first glance. The body in Don's car isn't Don, which begs the question: Could Don still be alive? If so, who has him?

Secrets abound in the Mercer household and Emma has had about enough of it.

But does Emma really think that she could pry the truth out of a secret that has been hidden for almost 17 years? Or will the secret Kristin has been hiding turn out not to be the biggest secret lurking in the Mercer house? Meanwhile, Sutton gets a glimpse into what Emma's life has been like when she is forced to pretend to be her sister while in Las Vegas.
