Oh god.. you can go to the website and read on their forums there...
Michael and Jin died when the Ship blew up. Locke goes into the cabin and see's Jack's father who can "speak" for Jacob, and Claire was there as well, who was shot by the bad guys from the ship, they also shot the French Woman, and her daughter...
The Island must be "moved", and Ben knows how. He won't let Locke do it, because who ever moves the island is "transported" off of it and can never return.
Sawyer jumps from the helo as its loosing fuel on its first run FROM the island, as it was shot at, he swims back and finds Julia drinking while sitting on the beach.
They realize the ship is going to blow up, they refuel, patch the holes, and Desmond jumps into the water a zodiac launches with some other people from the ship on it as well. The helo tries to go back to the island.. as they near it.. it goes POOF, just as they are about to run out of fuel again.
They drop a life raft, and do a water landing. They wait several hours and then spot a ship. Its Penny, going to the cooridnates she got triangulating Desmond's phone call. Thus saving Hurley, Jack, Kate, Sun, Sayid, and the baby Aaron.
In order to maintain the lie that they are the survivors and to go along w/ the news story of where the plain crashed... Penny has the ship go 3000 miles to the Indian ocean and drop them off in the zodiac w/ some pieces of wood for paddles.. they sit out in the sun for hours to get sunburned and aim for a small populated island.

Kate claims Aaron for herself and raises him as her own. Jack finds out some time later that Claire was his half sister, so aaron is techincally his nephew.
At the end Sun is in England, and is a business person for her father.. she meets up with Widmore, and says if he wants HER help to get back to the island OR at the oceanic survivors...she hands him her card...
Jack and the others were visited by Locke about a month before his "murder/suicide" and they are told they ALL have to return to the island. Jack breaks into the funeral home to look at Locke.. and meets Ben there.. he says, that yes they must return, and take Locke's body with them. Kate is visited by Clarie who warns her, "Do Not dare take Aaron with her." Jack was visited by his father.. and Hurley is having ongoing conversations with Charlie.
Sayid kills some one watching Hurley while he is in the mental hospital, and Sayid takes him to safety...not sure why there....
