The Bok family are gathered on top of a hill top where the matriarch is trying to help them regain their powers but they are all lackluster. Bok Dong hee, the daughter is overweight, the son Bok gwi ju indulges himself in alcohol while her granddaughter In ah does nothing but stick to her phone.
Before anyone knows what it’s happening, Bok Gwi ju suddenly jumps into the sea, while thinking of a woman. But a strange lady rescues him. He mistakes her for the woman in his head before finally collapsing.
His family take him to the hospital and Ms Bok realizes that she doesn’t have a way of contacting the woman who saved her son’s life. Do Da hae works as a physical therapist at a spa. When a difficult client appears for a massage, everyone is reluctant to attend to her, except Do Da hae who makes her feel so relaxed that she falls asleep. The woman is Ms Bok and when she sees Do Da hae and remembers she’s the one who saved her son, she’s so grateful. Do Da hae rejects the money she gives her so Ms Bok invites her to her home.
When Da hae arrives there, she is stunned by the beautiful residence. The family no doubt is very wealthy. Ms Bok welcomes her warmly. Meanwhile, Gwi ju wakes up from sleep in his dark scattered room. Despite the note fixed on his door by his mom warning him not to come out, he does so and ventures to the kitchen to get alcohol.
While trying to brew tea for Ms Bok, Da hae catches Gwi ju trying to uncork a bottle of alcohol. He doesn’t regard her when she tries to help so for some reason, Da hae purposely falls the bottle on the ground. She starts cleaning up. Ms Bok sees them and introduces Da Hae to Gwi ju as his savior but he doesn’t care and rudely tells Da hae to collect her reward money from his Mom and leave. He walks away and his mother follows, scolding him.
When they are away, Da hae secretly puts sleeping medicine in Ms Bok’s drink but feels like she is being watched. (Mmh…what is this woman up to?)
She starts massaging Ms Bok and in the process, tells her everything about her. She says she has no family and was divorced twice. In turn, Ms Bok tells her that Gwi ju married very young but his wife died in an accident. She says they share the same pain. However, it turns out most of the things Da hae said to Ms Bok were all lies because she has a mom who works at a local spa.
Ms Bok praises Da hae’s character to her husband when he returns from shopping, suddenly falling asleep while talking about her. She has a dream about Da hae wearing the family ring in her finger. When she awakes, she tells her husband who is surprised she had had a dream after a long time. Due to this, Ms Bok thinks Da hae is the one who would help the family regain their powers.
Gwi ju tries to talk to his daughter In ah, telling her he didn’t commit suicide but things are awkward between them as she leaves him outside her room.
At the gym Gwi ju owns, a beautiful woman enters with her resume to apply for the position of personal trainer. Gwi ju hires her without a care but Dong hee stops to interview her, doubting her resume but the woman is quite feisty.
Later, Gwi ju gives Dong hee money to help him buy a gift for his daughter’s birthday. Dong hee goes to her work at her Plastic surgeon clinic but her client leaves due to her being overweight causing her partner doctor to caution her. Dong hee feels bad staring at a cut out photo of what she used to be, slim and beautiful.
She goes to buy snacks but her card Is maxed out so she ends up using the money Gwi ju gave her for his daughter’s present to pay for the snacks. Just then, she gets a call to attend the birthday party of her neice but also to see the family’s savior.
When Da Hae arrives, she’s less than welcomed by Dong hee and Gwi ju. Meanwhile, Gwi ju gets angry with his sister for not getting his daughter’s birthday present but instead, using the money to buy food. Seeing her mother’s excitement, Dong hee points out that her mom wants to matchmake Gwi ju and Da Hae together. Hearing that, Gwi ju discourages Da hae by telling her that he already had a teenage daughter who would throw a tantrum should they get married. Not only that, his sister would be mean to her as he starts listing out Dong hee’s faults which makes her uncomfortable. Unable to stand it, Ms Bok takes Gwi ju away to speak to him privately while her husband goes to check on In ah.
In ah is quiet in her room, focused on her phone when her grandfather comes to check on her. He asks her to celebrate her birthday but she doesn’t react. She simply asks him if he prepared sea weed soup to which her grandfather says he did.
He’s preparing the soup when Da hae arrives to get water for Dong hee but she witnesses Ms Bok and Gwi ju arguing. She shouts at him to get his life back in order and stop mourning his late wife. Gwi ju is angered by the fact that she brought another woman to their home during In ah’s birthday but she responds that she only wants him to move on. In anger, she retorts that she had warned him not to marry his wife Lee se Yeon after she foretold that they wouldn’t have a future together but he was stubborn and went ahead to get her pregnant. Unfortunately, in ah hears them. She quietly blows her birthday cake before going back to her room. Gwi ju leaves the house in anger. In ah sees him from her room window feeling guilty that her parents lives got destroyed because of her.
It suddenly starts to rain and Ms Bok suddenly feels sick. She is taken to the hospital by her husband and Dong hee but before he leaves, the husband instructs Da hae to help him put off the fire where he was cooking Seaweed soup but Da hae seems to have a phobia for fire and is terrified of even nearing the gas. But In ah suddenly appears and turns it off for her. She then asks her if she put something in the food. Da hae realizes In ah saw her putting something in her Grandmother’s tea the last time so she lies that it’s a sweetener. Hearing her stomach growl from hunger, Da hae invites her to have a meal.
Meanwhile, Gwi ju visits his late wife Lee se Yeon’s memorial but her father is annoyed by his messy look and leaves in anger but her mother is more accommodating. She talks to him asking after In ah. He promises to bring her next time. His mother in law then advises him to live his life.
Da Hae makes In ah eat by distracting her from her phone. She tells her that her father didn’t try to commit suicide. Just then, In ah suddenly tells her that their family has superpowers but they lost them due to their modern diseases. Her grandmother lost her abilities to see the future due to insomnia. Her aunt could no longer fly due to obesity and her father lost the ability to go to the past because of depression and that she herself has no powers. Da hae simply thinks she’s joking.
Gwi ju comes back and finds Da hae washing the dishes. He’s surprised to still see her there. Da hae tells him she ate with In ah which surprises him because he knows In ha hardly eats. She tells him she knows that he lost his powers and that she’s aware he wasn’t trying to kill himself that day. He only wanted to retrieve the doll that a child had lost at sea. She calls him a hero but Gwi ju doesn’t believe he is. However, Da hae tells him he reminds her of someone who saved her life years ago. It’s due to that person she’s still trying to move on. She leaves after telling him to continue washing the plates.
Turns out, Da hae and her family, consisting of her mom, sister (the sexy gym girl) and uncle are scammers. She scammed her husbands into marriage and took their properties. She tells her family that the Boks have supernatural powers but they end up laughing at it. Their end goal is to make Da hae marry Gwi ju in other to take his wealth.
Gwi ju brings his daughter In ah a stuffed toy for her birthday before leaving her room. She dumps it among the bevy of others he had already given her as she recalls how the accident that changed her life happened. They were driving under a tunnel when her father, after giving her a stuffed toy, told her he would be back after saving someone and then he disappeared.
With a sad expression on her face, her mother continues to drive but then loses control of the vehicle. It swerves off the lane into a ditch. Gwi ju disappears back in the car only to find himself trapped in the accident scene as he desperately calls out the name of his wife and daughter.
