Segunda muerte (シーズン 1)

In a small town in Cantabria, a young auxiliary police officer finds the body of an elderly lady who has recently passed away. The mystery lies in the fact that it is the body of Juliana Cobián, who had passed away seven years ago. Who was buried in her place, then? When Juliana’s coffin is exhumed, another woman’s body is found inside: it is Soledad’s, Juliana’s daughter that, according to all the neighbours, had left the town twenty years before. What lies behind this second death?
