How will it all end? Before we find out, here's a chance to see how it all began! Out of the blackness, the first thing Jack (Matthew Fox) 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. Get ready for Season 6 right here on iTunes by seeing how it all began.

The castaways' spirits are temporarily raised with the discovery of a transceiver in the wreckage; the group discovers handcuffs, a gun and an animal that shouldn't be able to survive in a tropical climate.

Sydney confronts her mother, who discloses her true motivation, Sloane launches his grand plan, Will tries to figure out who set him up, and Marshall finds romance.

Sydney goes under cover to learn the location of a stolen NSA code-breaker; Vaughn fears that Weiss has been killed on a mission; Sydney and Jack argue over whether to tell Nadia the horrible truth about her mother.

Sydney's trust in Vaughn begins to fade when she finds out he's under investigation by the Agency. Irina is used as bait to catch Sloane, and Sydney welcomes Dixon to the CIA.
