Děj se odehrává v budoucnosti na válkou zničené Zemi a čtyři vyčerpaní vojáci obsluhují Sentinel - odlehlou vojenskou základnu v rozlehlém oceánu, který odděluje dva válčící kontinenty. Ačkoli jejich služba skončila před třemi měsíci, posádka pomoci stále nedorazila, a jak se prázdné týdny mění v měsíce, nastupuje paranoia, která prověřuje vztahy až k bodu zlomu...
In the year 2149, the world is dying. The planet is overdeveloped and overcrowded, with the majority of plant and animal life extinct. The future of mankind is in jeopardy, and its only hope for survival is in the distant past. An ordinary family goes on an extraordinary journey back in time to prehistoric Earth as a part of a massive expedition to save the human race.
Seeking the chance to build a better future, a group of courageous pioneers departs Earth for Carpathia, a newly discovered planet in a distant galaxy. Led by President Richard Tate and his core team of Stella, Cass and Fleur, the pioneers settle in the town of Forthaven, creating a society there alongside expeditionaries Mitchell and Jack. Having embraced all the challenges that come with forging a new beginning, the townspeople work hard to preserve what they've built on Carpathia, and even as they long for those left behind, there is optimism about the future. But while they try to learn from mistakes made on Earth, there is no avoiding the human pitfalls of love, greed, lust and loss.
