LOST

Lost is an American television series created by Jeffrey Liber, J.J. Abrams and Damon Lindelof. The series follows the lives of various individuals and groups of people, most importantly the survivors of the crash of a commercial passenger jet flying between Sydney and Los Angeless, on a mysterious tropical island. The series, which is divided in six seasons, had an enormous exit with millions of followers around the world.

The first season starts with a plane accident, lots of dead and a group of survivors who had to work together to stay alive. That group is immediately attacked by a number of mysterious entities, including a mass of black smoke “The Monster” and people known as “The Others”. Meanwhile, flashbacks, of each one of the protagonists, reveal their life after the plane crash.

In the second continues the problem between the survivors and The Others. New characters are introduced, who were survivors of the tail-section and they were in other neighbor island. Moreover, they discover a station built by Dharma Initiative, a scientific organization that was conducting experiments on the island decades earlier. In that station was a man, Desmon, who arrived here two years ago. As the truth about the mysterious Others begins to unfold, one of the crash survivors betrays the other castaways, and the cause of the plane crash is revealed.

In the third season, the survivors of Oceanic Flight 815 discover more about The Others and their long history on the island. The Others start to capture survivors and submit them to experiments. Finally, the survivors make contact with a rescue team.

In the fourth season the survivors try to make a deal with the rescue team, who arrive on a freighter and come to the island with dangerous intentions and without concern for the survivors. Meanwhile, flashforwards reveal the future actions of the Oceanic Six, a group of survivors who have escaped the island and attempted to resume their normal lives.

The fifth season follows two timelines. The first continues the original timeline, with the six survivors who left the island, and the second takes place on the island at year 1974 where the survivor who didn’t escaped are working with the Dharma Initiative. After three years the Oceana Six decide return to the island to save their friends.

The sixth season is divides in two lines, the first the present day of inhabitants of the island and the second shows their life if the plane had never crashed. In the final episodes, flashback shows the origins of the island's power and of the conflict between Jacob and the Man in Black, who are revealed to be twin brothers. One survivor becomes the successor to Jacob as caretaker of the island, and kills the Man in Black in a final showdown, with the island at stake. A small handful of survivors escape on the Ajira plane, the plane with whom they backed. A few survivors return home and others live happily on the island. The series finale reveals that the flash-sideways timeline was actually a form of limbo, where the survivors were reunited after they had all died.
