A longtime believer that she was the only person on Earth to survive a nuclear holocaust, Ann must confront the attentions of two men vying for her love after they mysteriously arrive at her home in the new "Z for Zachariah" trailer.

The film comes from up-and-coming director Craig Zobel and is adapted from the 1974 Robert C. O’Brien novel of the same name. Set in the aftermath of a nuclear war, "Z for Zachariah" stars Margot Robbie, Chris Pine and Chiwetel Ejiofor.

"Z for Zachariah" is scheduled for release this year.
