Lost - awarded the 2005 Emmy and 2006 Golden Globe for best drama series - has begun production in Hawaii on third season episodes of action-packed mystery and adventure -- that will continue to bring out the very best and the very worst in the people who are lost. The series will have its season premiere Wednesday, October 4 (9:00-10:00 p.m., ET), on the ABC Television Network.

After Oceanic Air flight 815 tore apart in mid-air and crashed on a Pacific island, its survivors were forced to find inner strength they never knew they had in order to survive. But they discovered that the island holds many secrets, including a mysterious smoke monster, polar bears, a strange French woman and another group of island residents known as "The Others". The survivors have also found signs of those who came to the island before them, including a 19th century sailing ship called The Black Rock, the remains of an ancient statue and bunkers belonging to the Dharma Initiative, a group of scientific researchers.

Jack, Kate and Sawyer open the season in captivity as prisoners of "The Others". Just who these "Others" are and what they want are primary questions Season Three will explore. Michael Emerson joins the regular cast in his ongoing role as Henry Gale, leader of "The Others". Romance looms on the horizon as Jack's interests veer towards a mysterious new woman, whose motives may be questionable. Sun and Jin will continue to celebrate their pregnancy - but is the child really Jin's? Locke and Sayid will band together with some of the other survivors and journey across the island in an attempt to free Jack, Kate and Sawyer. Charlie will attempt to return into the good graces of Claire and her baby, Aaron, but can he be trusted to stay clean and sober? The fates of Locke, Desmond and Mr. Eko in the aftermath of the implosion of the hatch are answered. Will Penny Widmore find the island and her long, lost love, Desmond, and can the survivors find a way to interact with the outside world?

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 60-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.
