Hierro - Season 1 - Episode 4
During a clandestine trip out of the island, Díaz discovers that Fran, just before he died, was trying to sell some valuable merchandise. He doesn’t know what kind of merchandise. And above all, he doesn’t know who was the partner from El Hierro who cooperated with him in the operation. This mysterious partner could be the murderer, because he is trying to get something from Fran’s environment (he broke into his and his mother’s houses…) Meanwhile, Candela feels the police investigation is progressing too slowly. The only person she trusts is Reyes. And in fact, the local police officer does discover (and us with her) who the murderer is. But she won’t live to tell the tale.

Synopsis
In El Hierro, the most remote island of the Canary Archipelago, a murder has occurred. Candela, an experienced judge with a strong character, must instruct the case as she takes up her position in a destination where she doesn't fit in. The island, an abrupt and changing landscape, is the home of a small community with singular traditions, where nobody enters or leaves unnoticed and where secrets are hard to keep. The murderer is surely one of the islanders. Everybody believes it is Diaz, a shady local businessman, who seems to fit the bill. But nothing is that easy, neither with Candela, nor with Diaz. They are both out to find the murderer. She is out to do her job to the best of her ability; he is out to prove his innocence.
