In a fun and romantic story, a woman named Ally finds herself at a crossroads in her love life. About to turn 30, she decides to take a look back at her past and realizes she has had 20 serious relationships. Terrified at the thought that she may have let the love of her life slip away, Ally embarks on a frantic quest to reconnect with her ex-boyfriends, hoping to find "the one" and avoid falling into the trap of a single life.
However, to her surprise, not everything turns out to be as she imagined. As she searches for and contacts each of her exes, she discovers that some of them are quite disastrous, while others simply do not meet her current expectations. Along the way, Ally encounters her neighbor, a charismatic and charming womanizer who, although he initially clashes with her personality, becomes an unexpected companion in her quest.
Together, they embark on a fun and often chaotic series of encounters and misunderstandings that lead them to question their own choices and desires. As the adventure unfolds, Ally begins to realize that love is not always found in the past; it might be closer than she thinks. Amidst laughter, romance, and touching moments, Ally must decide whether to risk opening her heart again or to stay in her comfort zone.
