In the late 1960s, Louie Jeffries, a young and ambitious district attorney, happily marries his beloved Corinne. However, Louie's life is tragically cut short in a car accident, and he finds himself in the afterlife pleading for another chance to return and be with Corinne. Through a bureaucratic error in heaven, Louie is reincarnated without his memories and is born again as Alex Finch. Fast forward twenty-three years, Alex grows up to be an energetic and charming young man with a bright future ahead. He crosses paths with Corinne's daughter, Miranda, while attending Yale University, and they form a connection, not knowing their shared history.

As Alex becomes more integrated into Corinne and Miranda's life, flashbacks and familiar experiences begin triggering hidden memories of his previous life as Louie. Struggling to make sense of these revelations, and with Corinne sensing an inexplicable bond with Alex, the situation becomes increasingly complex. Meanwhile, Philip, Louie’s former best friend who silently loved Corinne for years, grapples with Alex's sudden appearance. Tensions rise and relationships are tested as Louie/Alex tries to navigate his feelings and the unresolved emotions from his past life. The intertwined lives of the characters lead to a poignant and unexpected journey of rediscovery and love.
