As Paige grapples with her memory loss, Leo is determined to help her rediscover the love they once shared. He navigates the challenges of reacquainting Paige with their life together, hoping to reignite their bond. Meanwhile, Paige's estranged parents seize the opportunity to reinsert themselves into her life, pushing her toward the path she had originally chosen before meeting Leo. Torn between the familiar world of her past and the unfamiliar relationship she has with Leo, Paige must navigate her feelings and choices to rediscover who she truly is.
