Premise: From J.J. Abrams, the creator of "Alias", comes an action-packed adventure that will bring out the very best and worst in the people who are lost. Out of the blackness the first thing Jack 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.

Stripped of everything, the 48 survivors scavenge what they can from the plane for their survival. Some panic. Some pin their hopes on rescue. A few find inner strength they never knew they had-like Kate who, with no medical training, suddenly finds herself suturing the doctor's wounds. The band of friends, family, enemies and strangers must work together against the cruel weather and harsh terrain. But the intense howls of the mysterious creatures stalking the jungle fill them all with fear. Fortunately, thanks to the calm leadership of quick-thinking Jack and level-headed Kate, they have hope. But even heroes have secrets, as the survivors will come to learn.

Forty days on from the crashand the survivors have come to uncover many mysteries about the island - what is that strange beast of black smoke that roars and tears its way through the jungle? What are the significance of the numbers on the hatch, who exactly are 'the others' and what is their agenda? As time passes and everyone begins to get more comfortable, the group learn even stranger things are happening - especially when more survivors from the tail section of the craft emerge.
