Weol Joo is the daughter of a Shaman who possesses an ability to heal any person with grudges. In the old times, she is called a "dreamcatcher" as she resolves one's troubles by entering their dreams.

Five hundred years ago, Weol Joo treated many people in the village through their dreams. She healed the prince from his nightmares and woke up after a few days of treatment. She holds the hand of the person and enters their dreams as she comforts them. The queen heard wrongful stories about the spell Weol Joo made to the prince, prompting her to order the killing of Weol Joo and her Shaman mother.

Before the guards reached their place, Weol Joo's mother instructed her to leave the village to save her from death. Her mother gave her a binyeo to guide her and give her extra strength in times of hardship.

Weol Joo found out the guard burned her mother's house and as a cause of her death. Weol Joo went to the mountains and hung herself as she cursed the whole village to torment them with their dreams.

At present, Weol Joo existed as a shaman and opened up an old mysterious pojangmacha "Mystic Pop-Up Bar." Together with her is another shaman who assists her in completing her task to save her spirit from hell.

It's been six months that Weol Joo has not entered anyone's dream, which makes her frustrated and anxious. She has a bad temper as she deals with the human world. The yeomradaewang sent a final warning to Weol Joo. Within one month, she needs to complete and settle 100,000 people's grudges to save her spirit. Her atonement period cannot be extended as she remained in the living realm for 500 years.

Weol Joo got angry as she only had a short time to finish, and only a few people entered the bar.

Han Kang Bae works in a supermarket as a customer service. His ability and unlocked spirits allow him to let people talk about their problems when they touch him. This ability gives Kang Bae a problem since he was young. Even with bad intentions towards him, he would know as he touches the person they tell their story.

In the supermarket, any customers that Kang Bae touches would engage in a long chat with him about their life story. His co-worker has been recognized with good performance for the past five months. Later on, Mi-ran almost committed suicide due to work problems. Kang Bae invited her to go for a drink, and they entered the "Mystic Pop-Up Bar."

Kang Bae touches her hand, and she expressed her frustrations over their boss Mr. Park. Weol Joo offered her the potion drink, and she fell asleep. As Weol Joo fixes her trouble in Mi-ran's dream, Kang Bae joins her inside the realm with Chief Gwi. Mr. Park got his dose of medicine as Weol Joo beat him with kicks and punches for his misbehavior towards Mi-ran.

The mission completed, and Kang Bae and Mi-ran woke up the next day in their own house. Kang Bae is confused if he drank a lot or everything that happened is only in his dream. He found Weol Joo "binyeo" on the rooftop, which confirms that last night's encounter was for real.

Weol Joo needed Kang Bae as her magnet person to let people express their sad stories. While Kang Bae is convinced that Weol Joo will help him get rid of his mystical power. They realized that they need each other to get what they needed to do.

When they met again, Weol Joo was holding the binyeo tight, touching Kang Bae and relieved that she found the person she needed for a long time.
