In Chicago, the special collections librarian Henry DeTamble has a genetic anomaly that allows him to travel in time; however, he is not able to control the moment or the destiny of his voyages. When the stranger Clare Abshire meets him in the library, she invites him to have dinner with her in his favorite restaurant Beau Thai where she confesses that she has been in love with him since she was six years old. Henry leans that he had visited her many times in the real state of her parents and he falls in love with her. Soon they get married, but the life of Clare becomes troubled with the successive unexpected travels of her beloved husband.
