When boars raid the fuselage, Jack decides it has to be burned. Four days after the crash the survivors discover that their food is exhausted, and wonder what to do. Locke reveals the many hunting knives he possesses and suggests they should hunt boar in the jungle, and he, Kate and Michael set out to do so. Michael first enlists Sun to look after Walt until he returns. Sayid gives Kate the transceiver and asks her to find a signal.
In a flashback, Locke is at work in an office building playing a game of Risk during his lunch hour. His manager, Randy, taunts him when he discovers that Locke is going on an Australian walkabout, saying that there are things that Locke can't do in his condition. "Don't tell me what I can't do," Locke says angrily.
At home in his studio apartment, Locke is talking to a woman named Helen on the phone and tells her of his walkabout opportunity. He invites her to go to the walkabout, but she declines and says that she does not meet customers. She then tells Locke that continuing the conversation will mean charging for another hour, but that he "can't afford it". He says he doesn't care about the money, but she hangs up on him. Locke angrily hangs up his phone.
Michael is injured and Locke is thrown off of his feet while hunting, while Kate escorts Michael to the beach and Locke continues (after having a strange episode with his legs going numb apparently). Along the way she climbs a tree to use the transceiver, but when she sees the monster she drops it, and the transceiver breaks. Locke has a close encounter with the monster. However, instead of running from it, he stands his ground.
At the beach the castaways are clearing supplies out of the fuselage. Claire decides to lead a memorial ceremony for the deceased passengers. Boone suggests that Jack talk to Rose, who has been somewhat distant since their arrival on the island. Rose tells Jack that her husband, who was in the tail section of the plane when it crashed, is still alive. Michael and Kate return to camp. Sayid is angry that Kate broke the transceiver. When she goes to tell Jack about Locke, Jack sees a man in a suit walk into the jungle. Jack chases after him and Kate follows. They find Locke covered with blood with a slain wild boar.
In a flashback, Locke is in Australia talking to one of the leaders on the walkabout. He refuses to let Locke come because of his condition, saying it's too big of a risk for the insurance company. As the man gets up to leave, Locke is revealed to be in a wheelchair. In a flashback to minutes after the crash, Locke is lying on his back in the sand. He wiggles his toes, then slowly and clumsily stands up when Jack asks him for help with the man under the wreckage.
That night, Claire holds a memorial service for the dead passengers using information she found in their passports, wallets, and luggage. Charlie takes a hit of heroin before attending; his stash is running low. Jack is not among the group.
