Plot
While trying to secure a restroom key at a coffee shop, law student at Boston University Bea meets Goldman Sachs employee Ben. The two have an instant connection and spend the day together, ultimately falling asleep on Ben's couch. She leaves without waking him in the morning, but reconsiders and returns to the apartment, only to overhear him insulting her while talking to his friend Pete. Shifting back to Ben, who was incredibly hurt by this decision of Bea leaving, he gets up and decides to look at the “giant wrench” that he decided to tell her about. He does not tell anyone about his mom, although he did tell her because he knew she was special. Ben decides to tell Pete that he could not get her off him. When Bea is about to go back inside to talk to him, like her sister, Halle, advised her to, she is distraught by this dialogue. As Ben continues to degrade her to Pete, Bea turns around and leaves with her thoughts gathered about him. As she walks through Boston, she collects herself. [4]
Bea and Ben do not see each other again for six months, crossing paths when Bea's sister, Halle, begins dating Pete's sister, Claudia. The two are frosty toward each other, each blaming the other for their date ending poorly. Halle and Claudia later become engaged, and plan a wedding in Sydney.
Bea, who has broken up with her fiancé Jonathan and secretly dropped out of law school, is dismayed to find that Ben is not only on the same flight to Australia as her, but that they will both be staying at Claudia and Pete's parents' house in the days leading up to the wedding. Bea and Ben's disdain for each other begins to frustrate the other members of the wedding party, compounded by the appearances of both Bea's and Ben's exes, Jonathan and Margaret, respectively.
While Bea's parents attempt to push her to reconcile with Jonathan, the other attendees devise a plan to get Bea and Ben together to ensure the wedding goes off smoothly. Bea quickly sees through the scheme, and makes a deal with Ben to pretend that they are together in order to both make Margaret jealous and stop Bea's parents pushing her to make up with Jonathan.
Early efforts to sell the relationship are unsuccessful until a party on a boat, where Bea and Ben dance together and reenact a scene from Titanic , which ends in Bea falling into Sydney Harbour. Ben jumps in after Bea, and they have a conversation while waiting for rescue on a buoy. She tells him that she has withdrawn from law school, and they make a date to sightsee at the Sydney Opera House. They return to the house and have sex, but Bea suggests offhandedly that her recent actions have all been mistakes, which disappoints Ben. He slips away in the early hours of the morning, disheartening Bea.
The morning of the wedding, Margaret asks Bea for her blessing to rekindle things with Ben. Bea accepts, claiming that she was only situationally involved with him. Through a conversation with Pete, Ben indirectly reveals to Bea's parents that she has secretly quit law school, leaving her feeling betrayed.
After overhearing Halle and Claudia arguing, Ben convinces Bea to pretend to reconcile for the sake of the wedding. The ceremony goes smoothly, but Bea sees Margaret kissing Ben during the reception and leaves in tears, heading to the Opera House. However, Ben rejects Margaret and says that he no longer has feelings for her as he was wrongfully stuck on a memory. The wedding guests convince him to chase after Bea, so he jumps off a nearby cliff and into the Pacific Ocean, then convinces the rescue helicopter that retrieves him to fly him to the Opera House.
Ben apologizes to Bea, telling her that he left because he feared their relationship could become another regret. They reconcile and return to the reception as a couple, where Halle and Claudia reveal that their argument was yet another ruse to push Bea and Ben toward each other. Meanwhile, Jonathan and Margaret get together.
