Hierro

Candela, a strong-willed judge, is sent to the remote island of El Hierro, where as soon as she arrives, she is dealt a murder case.

Candela must decide whether to send Díaz to prison. Against the judgment of her team and the entire island, she releases him.

The investigation brings to light some dark points in Fran's life: he had dangerous contacts in the Netherlands and a mistress.

Díaz discovers something during a secret trip away from the island. Candela feels that the investigation is going slowly and only trusts Reyes.

Reyes is killed. When the alarm is raised over the disappearance of the local police officer, the island reacts. And so does Candela.

Reyes is still missing. A desperate Candela turns to Díaz for help who, like her, is determined to find the culprit.
