Intrigued, the crew continue to search the island, uncovering clues. Someone goes island nuts (a' la Locke) and begins to monkey-wrench the crews attempts to leave the island. There is a large explosion at some point and the crew and journalist find themselves back in 1982 or something and become imprisoned by Dharma initiative and interrogated. The rest of the movie is how they can ever piece together what actually happened to flight 815 and how they can return to their own time.
