Candela must decide whether to send Díaz to pre-trial detention. Against the criteria of her team and the whole island, she leaves him free with charges, although he is unable to leave the island and will be under surveillance.

The investigation brings to light some dark spots in Fran's life, as he had established mysterious contacts with someone in Holland and was having relations with a mistress whose identity no one knows.

On a clandestine departure from the island, Díaz finds out that Fran, just before his death, was trying to sell valuable merchandise. He doesn't know what it is and, above all, he doesn't know who his partner in the operation is.

Daniel starts to panic after killing Reyes. Taking advantage of the early hour, Daniel burns Reyes's car on a hill overlooking the sea. Then, back home, he hides the body under the buns.

Reyes does not show up, but the search operation leads to the location of a sunken boat that will provide new clues. It is a boat belonging to African diamond smugglers, whom Fran discovered while diving.

Diaz flees as he tries to avoid detention, but leaving the island without being discovered proves to be difficult. The police block exits from the island;.Candela conducts a tough interrogation.
