On the Island
Tim Harper, Sarah Lloyd, Zoe Vincent, Taylor Hughes, Evan Bailey, Kenneth Ellis, Monica Butler, Sharon Ford, Mark Kuznotsov, and Martin Fisher take off on a boat to get to Mortem Island. In the jungle of the island, Ryan Hughes and Gloria Cooper attempt to control the thirty remaining survivors, which includes Jackson and Grace Bennett, Terry Peterson, Sam Harper, Khloe Mills, Charlie Stewart, Caitlin Bailey, Julia Clarke, Zach, and Cody Vincent. As the sun goes down, Charlie and Caitlin are put to bed by Julia, who takes care of them while Ethan Stewart and Evan are gone, while Grace goes to her tent with Cody to settle down. However, suddenly a large roar is heard from inside the jungle which awakens the sleeping survivors. Gloria stays with the group, while Ryan, Jackson, Terry, and Zach go to investigate. The four follow the sounds to a single tree in the middle of a large grass patch. However, when Zach touches the tree, a dark substance swallows him and flies back into the ground. Ryan, Jackson, and Terry run back into the jungle in shock.

On Mortem Island
Tim, Sarah, Zoe, Taylor, Evan, Kenneth, Monica, Sharon, Mark, and Martin float up to the shore. The two get off the boat and are immediately met by members of ADA. Martin calls them and off and tells them they are here to make a trade. The nine survivors continue to hold Martin in their custody as the members of ADA bring them to their main base which contains the hospital. They find Ethan on a hospital bed with Dylan Evans watching over him. Dylan and Martin embrace as they reunite while Ethan is getting better, his surgery having just happened a few hours before. The survivors try to reunite with Ethan, though the ADA members prevent them from touching him. Sharon and Mark continue to hold Martin in their custody as Tim explains that they will give Martin back to them if they can have Ethan. Martin approves of the trade and convinces a skeptical Ethan, who believes that Martin should be dead. The survivors prepare to leave with Ethan until Martin quickly disarms both Sharon and Mark. Tim takes out the last gun and points it at Martin, until Dylan points a gun at Ethan. Tim realizes they failed and shoots Martin, though the bullet misses his heart and goes to his shoulder. Dylan proceeds to shoot Ethan before making sure Martin is okay. The survivors watch in dispair as Ethan dies in a matter of seconds. They try to escape but ADA takes them into custody after disarming Tim. The survivors are taken to the prison, where Dylan finds Tim and beats him in retaliation for shooting Martin. The next day, Martin, who is still recovering, reveals to Tim that he does not plan on killing any of them, but he plans on getting them to join ADA.

Flashforwards
Tim and his partner, Dave, arrive at a safehouse, where two men with a large sum of money are hiding. Tim and Dave manage to get back the money but one of the men shoots Dave, before Tim apprehend them. Tim arrests one, but kills the man who shot Dave. Dave is pronounced dead at the hospital, which causes Tim to sink into depression. Daniella Harper tries to get him out of it, but he only goes further after he discovers that the surviving criminal revealed what Tim did to the police. Daniella tries to support Tim but leaves him after he misses Olivia Harper's big softball game and he seems to not care before yelling at Daniella. Tim is kicked out of the house and begins living in his car. He calls a woman, who answers on the other side of the phone but Tim does not respond and hangs up. Eventually he drives to a bridge and prepares to throw himself over until Sarah drives up and stops him. Tim reveals that he was the one who called her the other day and she asks him why he is trying to commit suicide. Tim reveals that Dave died, his wife left him, and he has had to lie to say Sam has been dead the whole time, when they both know Sam survived the crash and they can no longer find him. It is revealed that instead of the usual flashback storyline, this is a flashforward, showing Tim's life after the island. Tim tells Sarah that he lives with the guilt everyday that he left his son, and Monica. Sarah tells him she has to get back to her baby and leaves him while he tells her that she is cruel for not feeling any remorse about leaving everyone on the island.
