Get ready for the Season Four premiere of Lost with a special presentation of the Season Three two-hour finale, "Through the Looking Glass," enhanced with on-screen facts and back story about one of the most talked about dramas on television. Whether you already watched the amazing conclusion of Lost last season or this is your first time viewing it, the special enhanced Lost catches viewers up on the story of the Oceanic 815 survivors in a way you've never experienced before. Be there for the enhanced Lost Season Three finale, Wednesday, January 30 at 9:00 p.m., ET/PT on ABC.

The enhanced version of Lost will include text on the lower third of the screen and will "let viewers in" on clues in the show, as well as give back story to catch new viewers up for Season Four.

With only 48 original episodes left until the final episode airs in 2010, this season truly is the beginning of the end, with the promise of rescue at hand. Jack has radioed a freighter stationed somewhere off the island. But when it's disclosed that Charlie's dying warning was that these people may not be who they say they are, the castaways are divided as to what to do. Jack is convinced that the freighter people are there to rescue them, while Locke is not. A split occurs among the survivors. Who is on the freighter? What was the significance of the flash-forward showing Jack and Kate off the island at some point in the future? What will the consequences be when the characters once again encounter Michael, who seemingly escaped the island after murdering two of the survivors? These are some of the questions Lost will explore during the action-packed fourth season.

The band of friends, family, enemies and strangers must continue to work together against the cruel weather and harsh terrain if they want to stay alive. But as they have discovered during their 90-plus days on the island, danger and mystery loom behind every corner, and those they thought could be trusted may turn against them. Even heroes have secrets.
