30 second overview of seasons 1,2 and 3 of LOST

In order to get this in in 30 seconds I will not talk about individual characters.

Plane crashes on tropical island. Survivors wait for rescue and think that they are alone on the island. They soon discover that they are not alone and the people who inhabit the island know a whole lot about the personal lives of those who survived the crash. Some survivors are intrigued by the mystical powers of the island while some believe that the everything can be explained.

In S2 more survivors are found, and some of the secrets of the island including a large abondoned science experiment is uncovered.

S3 lets the viewers in on more of the lives of the Others (those who were already there when the plane crashed), and how they are a blend of the abondoned science experiment and more that already inhabited the island and some who were brought to the island.

S4 has started to explore which survivors actually get off the island, their resons, and a rescue attempt that isnt exactly what it seems.
