"Lost: The Journey" is the clip show that originally aired on April 27, 2005, three weeks after the broadcast of episode 1x20 "Do No Harm", and 1 week before the last three broadcasts of the season beginning with "The Greater Good".
The first clip show created for Lost, it was notable in its attempt to present the events of Season 1 in a linear fashion. ABC intended the special to "bring new viewers up to date—but which current viewers will also find illuminating".
The show was repeated in the U.S. on May 21, 2005, between parts one and two of Exodus, narrated by Kate and Charlie in Australia.
Flashbacks of the core characters illustrating who they were and what they were doing before the crash, a look at the Island itself, and a preview of the season finale.
