The narrative of the episode primarily focuses upon Michael Dawson (Harold Perrineau, Jr.). Between the events of the second season finale, “Live Together, Die Alone”, and this episode, he becomes a spy on the freighter Kahana at the behest of Benjamin Linus (Michael Emerson).

The beginning of the episode shows two concurrent storylines. One storyline is set at the Barracks, the former home of the Others. During a community meeting, Ben confirms to several members of John Locke’s (Terry O’Quinn) faction that Michael is his spy. The second storyline is set on the Kahana. Sayid Jarrah (Naveen Andrews) confronts Michael about his purpose on the freighter.

The episode’s narrative is then shown in a continuous flashback. Michael has returned to Manhattan, New York City, and has become estranged from his son Walt (Malcolm David Kelley). He tries to commit suicide several times; he is unsuccessful, and is told by Tom (M.C. Gainey) that the Island will not allow him to kill himself. Tom gives Michael an assignment: he is to infiltrate the Kahana, owned by Charles Widmore (Alan Dale), who faked the wreckage that was found in the Sunda Trench, and kill any members on board. He is given a bomb to achieve this purpose. Michael attempts to detonate the bomb; it does not explode, and was used to show Michael that Ben does not wish the death of the unknowing crew members.

Appalled that Michael is working for Ben, Sayid turns him over to the captain of the freighter, Gault (Grant Bowler). The end of the episode focuses upon Danielle Rousseau (Mira Furlan), her daughter Alex (Tania Raymonde), and Alex’s boyfriend Karl (Blake Bashoff) travelling towards the “Temple”, a sanctuary used by the Others. Along the way, they are attacked, and both Karl and Rousseau are shot. To avoid being shot herself, Alex calls out to the shooter or shooters, who are not identified, that she is Ben’s daughter.
