The episode was directed by Eric Laneuville, and written by executive producers Damon Lindelof and Carlton Cuse.
Mr. Eko pulls a young girl (Emma) out of the water, and Ana Lucia Cortez performs CPR on her, saving her life.
Ana and Eko then go to aid more people, leaving the girl and her brother in the care of Cindy Chandler.
The man, "Goodwin", brings Ana to Bernard, who is still belted into his airplane seat, stuck up in a tree.
Ana manages to kill another one, who is discovered to be carrying an antique United States Army knife and a list of the nine to be taken, along with their descriptions.
The survivors move again and find a bunker marked by a DHARMA Initiative logo, with an arrow in the center.
While there, Ana reveals that she suspected that Goodwin is one of the Others, because on the first day, he ran out of the jungle with his clothes completely dry, ten minutes after the plane crashed into the water.
This shows the truth behind what Boone was hearing when he originally made the transmission in a previous episode from the first season.
Bernard asks how they would know their flight number, but Ana points out that they would know since Goodwin knew, and tells them to accept that this is their new lives.
The remainder of the episode is shown as a montage of the events already seen in the episodes "Orientation" through "Abandoned", including the tail-section survivors' acceptance of Jin, Sawyer and Michael, the trek to the midsection's camp, Sawyer falling ill, Cindy listening to the forest's whispers just before she is "taken", and the shooting of Shannon by Ana Lucia.
