The episode begins its narrative in late December 2004, over ninety days after the crash of Oceanic Airlines Flight 815. The battle between the crash survivors and the dangerous and mysterious island inhabitants referred to as the "Others" comes to a head as ten of the Others attack and are then ambushed at the survivors' camp and are subsequently killed. Meanwhile, Jack Shephard (played by Matthew Fox) leads most of the survivors to the island's radio tower to communicate with a nearby ship. Intercut with this story are off-island scenes spotlighting Jack, who has become suicidally depressed and addicted to painkillers.
