Once upon a time, a plane crashed on a deserted island. Or, at least, that's what they thought. Time passed, people died, things happened. A young mother had her son Aaron on the island, a couple found each other again, and people made friends. Over three years, some stayed on that island, either dying, or getting off the island at last moment.
And now, it's like the island wants more victims. Oceanic Flight 481 has crashed onto an island; time passes, people die, and things are happening. Most unaware of what had happened before on this island, mysterious things are happening, and no one knows how, or why. The people split into two groups, and as the groups seem to get further and further away, things get stranger and stranger.
