High school English teacher Abigail Brennan-DiBlasi can't imagine life without her husband Joe. After 25 years of marriage and four children they can finish each other's sentences, but their once vibrant and loving union is disintegrating. It seems fear has replaced love as the emotion that keeps them together and their bitter verbal battles make Abby long for something else. As she watches the sunset through the maple tree in her backyard, she feels the sunset is beckoning her to another life and she fantasizes about a man who is Joe's opposite.
A trip to Los Angeles is exactly what Abby needs until she gets more than she bargained for with a serial rapist on the loose and an encounter with handsome Detective Kristoffer Larsen who interviews her as a potential witness to a rape. Sparks fly between Abby and Kris, and they begin a whirlwind romance. But years of dealing with rape, domestic violence, and child abuse as a member of the Special Assault Section of the LAPD have taken their toll on Detective Larsen and he is haunted by his past: a fiancee's unsolved murder, a partner's death, and the incarceration of his police officer father. Abby's years with Joe also threaten the pair's budding relationship for Joe can still tug at her heartstrings. As Kris and his colleagues get ever closer to capturing the elusive rapist, Abby must look into her heart to discover the promise the sunset holds.
