The episode centers on the character of John Locke (Terry O'Quinn), who in flashbacks is revealed, in one of the first plot twists of the show, to be paralyzed from the waist down as he attempts to join a walkabout tour. On the present day events, Locke leads a hunting mission after the wild boar in the jungle as the food supplies of the Oceanic 815 survivors starts to shorten, while other survivors decide to burn the plane's fuselage.
