After the disappearance of a plane and it has been long time, people believed that it fell down into the sea. After five years for the ordinary people, the plane suddenly returns but the time for the passengers have passed as some hours not five years. They try to do whatever they can to keep up in their lives and their darlings as five years is such a long period.
Self-important much? There's an awful lot of big emotion on this show, which is my polite way of saying that it's pretty soapy... But there's a "Lost"-like mystery afoot that drew me in, as the passengers begin to experience similar after-effects.
