Harriet's existence is a relentless cycle of sorrow, forever haunted by the tragic car accident that claimed her boyfriend, Max, two years ago. Her grief becomes even more complicated due to an unusual affliction: whenever she hears songs associated with their time together, she is inexplicably thrust back into those moments. This phenomenon often manifests as a seizure in the present, leading Harriet to take drastic steps such as wearing noise-cancelling headphones in public to avoid these unwanted temporal excursions.
As she strives to navigate her path toward emotional recovery, Harriet continuously seeks ways to alter the past and save Max's life. During one of her temporal journeys, she confronts him with a profound question: > "Would you sacrifice our entire relationship—our love—if it meant securing your survival?" This inquiry weighs heavily on her, forcing Harriet to wrestle with the complexities of her situation.
In a support group designed for those grieving lost loved ones, Harriet encounters David Park, a fellow soul grappling with the loss of his parents while trying to maintain their antique business. As a bond forms between them, Morris, a close confidant of Harriet and her sole ally in time travel, encourages her to consider moving past her memories of Max and opening the door to a new chapter in her life.
However, when social events become abundant, Harriet finds the allure of reliving treasured memories irresistibly compelling. A song that triggers her emotional responses sends her spiraling back to the enchanting moment she first met Max at a concert, where their impulsive connection blossomed. In the present, she shields her heart by dismissing David's queries regarding her enigmatic headphones, opting to keep her temporal journeys a secret.
As their relationship deepens, Harriet decides to share her extraordinary abilities with David. Initially met with skepticism, he eventually recognizes the truth in her revelations. This realization confronts them with a critical question: can love truly transcend the boundaries of time? For Harriet, this leads to an intense introspection—though she has grown to love David, she cannot ignore the poignant truth that had Max survived, their paths might never have intertwined. These reflections prepare the stage for a heart-wrenching examination of what it means to change one's fate and the sacrifices required in the quest for happiness.
In this reimagined landscape, Harriet’s world has evolved; the headphones that previously safeguarded her from overwhelming stimuli now collect dust, symbols of a past fraught with anxiety and indecision. Amidst this transformation, Max unexpectedly appears, arm-in-arm with another woman, radiating an aura of contentment. Yet, in this serene tableau, neither Harriet nor Max notices each other, too entangled in their individual conflicts.
In a twist of fate, Harriet and Morris attend a concert, engulfed by the vibrant energy of live music. As they sway to the rhythms, David and his sister occupy nearby seats, their faces illuminated by shared delight in the performance. In this joyous atmosphere, Harriet’s eyes lock with David's, igniting sparks of connection that resonate deeply. This fleeting moment will soon propel a series of events that will indelibly change their lives.
