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.

On Halloween, the team investigates a string of murders that mirrors stories from well-known Hawaiian folklore. Meanwhile, Grover pays a visit to a man on death row who may hold the key to an old case.

Jack is nearly delirious from lack of sleep and struggles to overcome the haunting events that brought him to Australia and, subsequently, to the island.

When the task force's long-time informant is accused of murder, McGarrett brings in an old friend to defend him.

An escaped convict who wants Five-0 to prove his innocence abducts Danny and McGarrett, and Grace punches a person at school.
