Abrams, the creator of Alias, and Damon Lindelof (Crossing Jordan) comes an action-packed adventure that will bring out the very best and the very worst in the people who are lost.　　Out of the blackness, the first thing Jack (Matthew Fox, Party of Five) senses is pain. Then burning sun. A Bamboo forest. Smoke. Screams. With a rush comes the horrible awareness that the plane he was on tore apart in mid-air and crashed on a Pacific island. From there it's a blur, as his doctor's instinct kicks in people need his help.
