Lost - Season 1 - Ep. 15-25

It follows the lives of plane crash survivors on a mysterious tropical island, after a commercial passenger jet flying between Sydney, Australia and Los Angeles, United States crashes somewhere in the South Pacific. Each episode typically features a primary storyline on the island as well as a secondary storyline from another point in a character's life, though other time-related plot devices change this formula in later episodes.
