Twenty-five-year-old Olivia Marshall moves in with her brother Jack Marshall in Omaha, Nebraska after she burns down her Chicago apartment building. Jack tells Olivia she can stay for a month so she doesn’t have to move back in with their parents while she’s getting back on her feet. One night, she’s sitting on the kitchen counter, drinking beer and eating pretzels when she gets a text from a number she doesn’t recognize. The texter, Mr. Wrong Number, asks her what she’s wearing. Olivia plays along, replying with a joke. He admits he’s gotten the wrong number. They send a few more jokes back and forth before saying goodnight.

Early the next morning, Olivia’s mom Nancy Marshall calls to ask when she’s coming over and if she deposited the money she loaned her. Olivia stumbles into the kitchen for coffee, where she bumps into Jack’s high school friend Colin Beck. She’s shocked by how attractive he’s become and even more surprised to learn he lives with Jack. Olivia knew Colin growing up, but Colin always teased her. When he asks about burning down her apartment while “burning love letters on [her] wooden deck,” Olivia feels embarrassed that he knows the story (11).
