In a small Italian town, two baby girls are born on the same day but are accidentally switched at the hospital. For years, they live in two completely different worlds, unaware of the mix-up. When the mistake is discovered, it sets off a series of emotional events that challenge the bonds between parents and children, as well as the girls' sense of identity.

Will love and understanding prevail, or will the truth drive the families apart? Sorelle per Sempre masterfully weaves these questions into an unforgettable narrative.
