A romantic trip to China turns into a lunar nightmare for a pair of happy newlyweds when their taxi driver ditches them in a remote village, and the locals offer them up as sacrifices for the menacing moon creatures that return to Earth annually to replenish their ranks. According to Chinese legend, the dead return to Earth on the seventh month of the lunar year, when the moon glows full in the night sky. America-born Yul (Tim Chiou) and his new wife Melissa (Amy Smart) had just arrived in China to meet Yul's family when their idyllic getaway takes a sudden turn for the worse. When night falls and their tour guide leaves them stranded in a darkened, boarded-up village, Yul and Amy quickly realize that this wasn't a planned stop. Once a year, the lunar creatures return to Earth in search of a sacrifice. Yul and Amy have just been offered up, and now in order to avoid being assimilated into the collective that pursues them through the darkened forest, they will have to survive until the morning light casts the frightful beasts back to the moon for another year.
