The movie opens with the definition and possibility of a wish coming true. And the first location is in the big city. There's a red carpet event and Maddie gets out of the taxi and her scarf gets jammed in the door while her attention is Paul. She suddenly twirled around and screams "that's my scarf." She approached Paul and he invites her to take a picture with him. And he introduces his editor to the crowd. While waiting for Paul to finish she receives a phone call from her mother- who is complaining about bathroom tissue because the students keep stealing it.
Her mother wants to know if she had that talk with Paul. Maddie warns her not to tell anyone about her feelings for him. She tells her mom her friends don't know. Her mom says if her friends don't know neither does he. Maddie thinks Paul has something important to tell her and perhaps its about him liking her too. She ends the phone call and all her attention is for Paul.
She greets her friends and she tells them her scarf is probably in Brooklyn by now. Her friends tells Maddie she practically wrote the book. And they ask if he's single and there's laughter. She goes to talk with Paul at the bar and he says he wants her to work with him on his next book. She's disappointed and says, "sure." He bumps into her friend and helps her with her fake eyelash. They both show chemistry between each other and Maddie immediately takes Paul away with her to meet and greet people.
Paul reads a chapter from his novel and surprisingly, Maddie knows each chapter of the book and knows the story well because she wrote it. She sees Paul glance at her friend and then they sit together while he continues to sign novels. Paul asks how they know each other? And they both say from school and her friend says she was a big reader. Maddie whispered to her other friend and said, "that was me." She asks if the cover of his book is a real place and he says, "Yes...it's near his parents home." Her friend says she would love to see it sometime and he says he would love to take her there.
Maddie and her friends take a taxi together and her friend can't stop talking about Paul. Maddie feels terrible about everything that occurred. She says Paul signs a lot of books. The book is titled Two Irish Hearts. Her friend says, "and with his phone number?" And surprisingly its his real number. Maddie is more angry and uncomfortable about the situation. Then months passed and her friend is getting married in Ireland. Maddie receives an invitation to Paul and Emma's wedding and boy is she mad.
At the Ireland airport, Maddie sees her luggage and a guy grabs the same one and says, "this is my luggage," and Maddie says no its hers. He was on his phone and says, "I'm going to to go...There's an American woman trying to steal my bag." They both struggle with the bag and it opens revealing its really his. She accidentally holds his boxers. Maddie has to file a claim for her missing luggage and tells Paul she will catch a cab. She stands outside only to discover there's no Ubers in town. Then a cute little bus arrives and e says he can take her to Paul's family estate. The guy with boxers gets on the same bus.
Maddie aks him if he's a photographer and he says yes. They talk about her friends wedding and he says perhaps she'll catch the bouquet 💐. And she says she's not interested in getting married. He said it was a stupid joke. Her book falls out her bag and he saysare you enjoying that. And she said Paul Kennedy is one of the bestselling authors in the UK. He says and they sell a lot of fish and chips but it doesn't make them good. The bus driver says Kennedy house is here Ma'am. She tells the photographer he can go and ****.
The Kennedy estate is huge and while approaching the house, she hears a guy say, "you're trespassing you know." And she tells him actually she is Maddie and he jokes and says he knows exactly who she is and tells her he's the brother and introduces himself. She enters the home and Maddie almost causes a vase to fall but she catches it. She lies when they say Maddie should be happy for Emma and Paul.
The photographer enters a pub and has a room there. He's in town for some sheep-shearing festival. Back at the Kennedy estate Maddie looks out her bedroom window and says, "beautiful," and looks at the couples photo and desires even more now if Paul was hers. Her other friend notices her demeanor and says she looks rather off. The happy couple planned a picnic for their guests. While everyone else paddles a boat, Maddie goes for a walk. She walks over a brook of water and finds a beautiful tree 🌳 that has some large stones around it. She talks to her mom and said she should have told Paul how she felt and wish he was marrying her.
Then suddenly a woman appears and says, "Was that a wish you were making?" She said no she was on the phone. The woman says that's a wishing chair and in order to have a wish, you must sit on the chair properly. Maddie says no...She's good. And the woman says, "what are you afraid of? Maddie says she doesn't believe in that kinda thing. And the woman says, "Well you have nothing to lose." So she properly shows Maddie how to make a wish. "Close your eyes and mean it." Maddie says, "I wish I was marrying Paul Kennedy. Well it didn't work." And the woman said, "didn't it. How could you tell?" Maddie says, "Isn't there supposed to be an earthquake or a lightening bolt or something."
The woman makes a stiff breeze and Maddie is surprised. She gently falls back, and suddenly appears in a bed. She gets up and is surprised to see Paul nude in the shower.
