As soon as Ally woke up next to a random guy in her bed, she quickly made her way to the bathroom and did some touch-up so she could look sexy. She cooked breakfast for him and asked if he’d come with her to her sister Daisy’s wedding, but he said no and left. Later that day, Ally lost her job at the office. On the way home, she read a magazine article about a survey which said 96% of women in the USA have an average of 10.9 lovers – this number seemed low to Ally until she counted how many guys she had slept with: 19.
Ally decided she wouldn’t increase her “number” and settle down. At her sister’s engagement party, she drank too much and ended up sleeping with her boss, who fired her. So, according to her decision, she had to marry this guy—but soon realized she didn’t want to. How could Ally keep her number from increasing and still find the love of her life? One way was to stay in touch with all the guys she’d dated so far and get back together with one of them.
A guy next door promised Ally he’d help her find all of her ex-boyfriends. Colin was like Ally, sleepin’ with new people now and then. He was a handsome dude who hit on her straight up, but Ally had decided not to cross that line. To avoid girls in his apartment, Colin sometimes hid in Ally’s room and she would act like his girlfriend to get rid of them. This mutual aid developed their friendship. With Colin’s help, Ally started meeting all her exes – everyone seemed even more attractive than before, but it didn’t change the reason why their relationships hadn’t worked out in the first place. Still, she kept trying.
Ally’s sister and friends warned her about Colin and told her why he was like the other 20 people she had been with. The only one left was Jake Adams, a rich guy from Ally’s college. Colin couldn’t find him. Ally and Colin became close; they accepted each other’s lifestyles and interests without judgement.
One day, Ally found out that Colin had lied about knowing Jake’s whereabouts. She got angry with him and stopped talking to him. When she met Jake—the “perfect” guy—he seemed successful, rich, and ambitious. But he didn’t take Ally seriously and left in the middle of Daisy’s wedding party.
After all this, Ally realized that Colin was the guy who never judged her. He appreciated her just as she was. Though they were close, Colin respected her decision not to have sex with another guy and increase the number. This part was a little dramatic: Ally rode a bicycle wearing a dress, searching for Colin everywhere. Finally she found him and confessed her love. When she woke up next to Colin in the morning, she got a voice message from one of her ex-boyfriends confirming they had never had sex while dating each other. That technically allowed Ally to find love without breaking her promise!
