Erik, a recovering alcoholic, wants his share of the inheritance from their late father. However, his presence quickly unearths a much deeper deceit between them – a terrible accident from their past, which Alma has desperately tried to suppress. With the ceremony impending, Alma is haunted by resurfacing trauma and all that was previously invisible is now written on the walls.
