Casey is the story of David and Keith, two men taking their long-distance relationship to the next level when David moves into Keith’s home. The house feels cold and surprisingly unwelcome to David, evidenced not only by new tension between the two, but also by strange occurrences suggesting the presence of a third man in the relationship: Casey, the partner who went missing five years before. As the specter of Casey seems to grow stronger, the strength of David and Keith’s bond is tested to the near breaking point.
