Maddy works as a doctor in a small resort town, where she lives happily with her ten-year-old son, Esteban. But one sunny summer morning on his birthday, Esteban ran to the bakery — it was only about 150 meters away — and disappeared without a trace…
Ten years passed. The police long ago closed the case, declaring the boy dead, but Maddy refuses to come to terms with losing her son and still believes Esteban was kidnapped. She left the seaside town and tries to live on. Suddenly, some force makes the heroine return to that beach where she had last been with Esteban. There, Maddy meets a boy who looks like her son to the last detail — the same appearance, the same age, even the same swim trunks. And for her, time seems to stop. Is it really Esteban — or his reincarnation? How do you explain an absolutely supernatural resemblance? From that moment on, an obsessive idea takes hold of her. How far is Maddy willing to go to find out the truth? And why does she have this feeling that the boy is in danger and must be saved?
