Hierro - Season 1 (2019)

During a clandestine trip out of the island, Díaz discovers that Fran, just before he died, was trying to sell some valuable merchandise.

The murderer, upon being found out, kills Reyes. From that moment on, he faces the difficulty of getting rid of the body in an island like El Hierro, where it is difficult to vanish without trace.

Reyes hasn't been found, but the search operation leads to tracing down a sunk boat which will provide new clues. The boat was used for smuggling African diamonds, and was found by Fran in a diving excursion.

Díaz avoids being arrested by desperately fleeing. But leaving the island without being found out is impossible, especially with a police operation that shut up firmly the few available exit routes from the island.

The murderer, taking advantage of the chaotic situation during the Descent, manages to get hold of the diamonds. But now he must face a new obstacle.
