The girl has gotten an internship at The Globe as part of a program from Boston College. Right before she starts, however, she gets an invitation from an old love interest of hers, asking if she wants to go to Barcelona with him.

She says yes, makes an excuse for why she can’t intern, and heads to his apartment with her bags. On the way in, she sees another girl leaving, which he explains later as another love interest whom he was only having for the time being. They then spend the day together and have sex the night before going to Barcelona.

She says no and goes to her internship as usual. When asked, in a group, about her interests, she says she wants to go on the crime beat. She then starts investigating a series of seemingly isolated stalking and rape incidents in her town, specifically one incident where a woman jogging was raped by a lake. Nothing suggests a connection at first, but the girl is determined to find one. She goes to her father’s police station to look at police reports of each incident, but she can’t figure it out yet. Meanwhile, her editor isn’t worried about whether his interns will ever produce a story this summer; it’s all just for experience.

In the world where she says yes, the girl is excited to go to Barcelona and watches videos of it before going. When she gets on the plane with her old love interest, she knows it’ll be a great summer.

In the world where she says no, the girl notices her editor getting uncomfortably close to another intern. Wanting to talk to her, the girl invites the intern over to her place to have Chinese food. Together, they talk about their internships but don’t broach the topic of the editor. Eventually, the intern asks the girl about the case she’s working on about the stalking and rape incidents. The girl doesn’t yet have a lead, but eventually the intern recommends her to dine at an Italian restaurant close to where the jogging woman was raped.

In the world where she says yes, the girl and her old love interest move into a luxurious hotel and spend the next few weeks seeing everything there is to see. They enjoy long walks and family restaurants. They have sex most nights. One day, they go to Montserrat and spend a day in its history and architecture. After three weeks, the girl decides to stay in one day and gets to know a hotel maid while the old love interest is out. Later that day, they rejoin at dinner, where he talks about the Spanish Civil War and she tries to talk about the hotel maid.

In the world where she says no, the girl goes to the Italian restaurant, claiming that she’s a journalist writing about food. She talks with and slightly interviews all of the staff, subtly gathering their alibis for the day that the jogging woman was raped. She notices a discrepancy in the bartender’s alibi, as he says that he was already working at the Italian restaurant in the morning even though the restaurant opens at eleven and he isn’t asked to come in until later in the afternoon given that alcohol isn’t served often early. She runs the bartender’s name at the police precinct and finds out he has a history of sexual offenses. The police then run his DNA against the jogger’s rape kit and find a match. Everyone at The Globe celebrates.

In the world where she says yes, the last stretch of the Barcelona trip wanes in excitement and becomes awkward. The girl doesn’t want to have sex with her old love interest. She wants to go to the village where the hotel maid came from, but he isn’t that fascinated. She goes anyway and enjoys the food there. On the way back, she thinks about how great the trip was and tries not to think about how much she was sexually used and humiliated in exchange for it. She wonders what things would be like if she took The Globe internship instead.
