But life has other plans—his relationship ends, his projects are abandoned, and he loses tenderness and poetry in his soul. Meanwhile, Jade imagines her life would be happier if she had married him 20 years earlier. When they meet again, Jade seeks the lost parts of Lucas' youthful self. The clone appears as an unexpected love triangle: Lucas becomes a rival of himself. The arrival of the clone dramatically alters their lives.
