Mystery 6 Episode 3

Donghae is distracted at dance practice. To cheer him up, the members have a freestyle dance session. Leeteuk suggests they seek professional help to determine why a ghost is haunting Donghae. An exorcist is called in, and she informs Donghae that the spirit is very evil and vengeful. To cheer him up after hearing the bad news, Kangin takes Donghae to the gym. Reading the later entries in the diary, the girl Park Gayoung has more violent dreams, and blames it on her father. She writes that she starts seeing and hearing things. Super Junior rehearse for a live performance of Miracle, but because of eerie ghostly noises from the music, they are forced to instead lipsynch. They are informed by their manager that Gayoung was murdered by an intruder. Shindong, Eunhyuk and Kangin make kimbap for Donghae, while Sungmin and Ryeowook go to the recording studio. Suddenly, the power is cut off and Sungmin is briefly trapped inside the recording booth. When the power returns, the crew take a picture for the technician's birthday. Doing this, they capture the figure of the ghost standing behind Sungmin in the photograph. (Source: Wikipedia)
