Behind the Wall (2008)

At the age of eight, Catelyn found her mother murdered in his lighthouse-renovated home. Although the motive was unknown, Catelyn's father Chris was arrested in the name of the killer, which unfortunately drove Chris crazy and made Catelyn move out of his hometown. Twenty years later, when the builder bought the abandoned lighthouse, Catelyn found that the builder was missing one after another. It turned out that grandfather had left a family secret here, and Catelyn had to find out the truth in order to prevent more misfortune from happening.
