O.T. ผี Overtime

Karan and Tee are the two business owners who worked overtime late into the night, played horror pranks on their employees, only to be scared the lives out of them by the real ghosts haunting their office. Now Karan and Tee cannot take the elevator at night. They are paranoid and keep checking if the person working near them is human and not a ghost. But something remains the same: they still have to work overtime late into the night, and they still can’t help pulling the legs of their employees with their latest tricks. The company faces bankruptcy crisis until someone came along and offered them a project that will save them from the brink of closing down. This "project" would be a one night adventure to one of the top 5 most haunted hotels in ASEAN.
