Lin is a young woman who lives in a small mountain village in China. In the surroundings of her village there is a temple that rarely anyone dares to enter after the sun has gone down. After sunset the night butterflies appear that do not allow people to enter inside the temple. Lin believes that the butterflies are ghosts of her ancestors.
Who doesn’t want to believe that our beloved but deceased family members aren’t looking out for us or with us in our times of need? Lin truly believes she has to communicate with the spirits and that she has to make a pact with them instead of be scared of them. So, Lin begins her mission and she needs some extra help.
