As Emma, Ethan and Thayer continue to search for the truth of what happened to Sutton at the lake, they follow a lead that raises more questions than it answers. But when a poorly-timed encounter threatens to expose her identity, Emma is left in a precarious position that turns her life upside down. Will she be able to recover?

Meanwhile, Laurel impresses the crowd at her mom’s charity benefit with her musical talents, and Rebecca and Alec get to know each other better.

Ethan insists on helping Emma get the answers she's looking for about her twin sister. So when a tattoo sparks a memory about Sutton, Ethan pursues an explanation. But the information proves costly when Ethan heads into a situation that quickly gets out of control.

Meanwhile, Mads sneaks off to see Ryan, and Laurel continues to see Justin against her parents' wishes.

When Ethan is implicated in a serious crime, he and Sutton leave town and hide out with his father, Ben, on the reservation where he grew up. A burgeoning tension between father and son has Sutton playing mediator, but, despite the awkwardness, she appreciates seeing a side of Ethan that she did not know when they were together.

Meanwhile, Emma is left to deal with the aftermath of Ethan’s situation when she must pretend to be witness to a scene where she was not present.

Ethan is still a wanted man in hiding with Sutton, leaving Emma to worry if justice - and love - will prevail. Discouraged by Dan's inability to crack the case, Emma takes it upon herself to find a way to vindicate Ethan. With the help of Mads and Thayer, they search for any lead that may help prove Ethan's innocence. Meanwhile, Ethan and Sutton's time alone in hiding together has lowered Ethan's guard. Sutton uses the opportunity to encourage Ethan to bond with his estranged father, looking to heal her relationship with him at the same time.

And Alec questions Rebecca's motives after she agitates Ted and Kristin by offering Laurel the opportunity to produce a music demo.

Caught by the FBI, Ethan is brought back to Phoenix to face charges for murder. As Emma continues to search for evidence that can help Ethan’s case, she clashes with Ted and Kristin over her unwavering support of a murder suspect. Alec’s relationship with the victim prevents him from taking the case himself so he assigns a star prosecutor from his firm, prompting Dan to reach out to an ex-girlfriend who is now a successful defense attorney.

Meanwhile, encouraged by their time together in hiding, Sutton has her own plans for Ethan.

Emma wants to find out what really happened on the reservation but Ethan is avoiding her and Sutton is looking to send her packing for good. Curious about his father’s possible link to Derek’s murder, Thayer starts to doubt Alec’s alibi and begins investigating Rebecca’s past. And, Kristin grows increasingly suspicious that Ted is not telling her the entire story when it comes to Justin’s mom.

An unexpected engagement leads to a quickly-planned wedding, causing suspicions that something is awry. Sutton encourages Emma to show Kristin what they found in Rebecca's house. And Ethan makes a discovery that changes the game.

Meanwhile, a shocking revelation leads to major repercussions in the Mercer household.

Alec is in jail after his arrest for murder, but he still manages to unnerve Emma. Rebecca and Sutton formulate plans for the Mercer family.

Sutton steps up her plans to win back Ethan, and makes a point to let Emma know her intentions. Feeling left out of Emma and Thayer's growing closeness, Mads visits her father in prison and shocks Emma with a family revelation. Dan continues his investigation into Derek's murder, regardless of Alec's arrest, and Jordan starts at his new school and tries to get close to Laurel.
