La Unidad (HBO): 

Episode 1

After more than a year of exhaustive searching, the police investigation unit led by Carla Torres managed to arrest Ismail Hamid, a crucial figure for locating one of the most sought-after Jihadist leaders. However, the first-born son of Granada-based Syrian businessman Omar Al Hassan, who has links to the Jihadist movement, dies during the operation. Broken by grief, Al Hassan sets up a hit against Carla and Sanabria to avenge the death of his son.

Episode 2

Following the deaths of Sanabria and Sergio in terrorist attacks, Carla is given a police protection detail and needs to keep a distance from Lua to avoid putting her in danger. Devastated by the deaths of their colleagues, the remaining members of the Unit search for the members of the terrorist cell: Nahila and a mysterious man who they are unable to identify. But as far as Al Hassan is concerned, vengeance is not yet complete, and on seeing how difficult it is to reach Carla now he orders an attack against Marcos to get her to come out of hiding.

Episode 3

Marcos’ apartment comes under fire while he’s in bed with Kala, another colleague, and Lua is sleeping in her bedroom. Aware that all of them could be targets, he assigns a police protection detail to all the members of the Unit, who also need to face up to the fact that there could be a mole among them. Finally, they manage to identify the mysterious man: it is Fennec, Nahila’s brother, a former soldier they assumed was dead.

Episode 4

The Unit has managed to bring Fennec’s children to Spain and has organized a huge surveillance scenario in the hope that at some point he will go to visit them. While waiting for their trap to tempt the prey, they manage to find out that Nahila received a lot of money from someone who is financing her cell, but the search for the possible mole dries up. The plan to catch Fennec works: he arranges a meeting with his children. But at the last moment, someone sends him a message and he manages to evade the police.

Episode 5

Fennec’s escape confirms that there is a mole in the Unit. This realization leads them to Kala, who is roughly detained and questioned by Marcos, though she maintains her innocence throughout. Al Hassan issues instructions to carry out the final hit on Carla. However, a mistake by the true mole reveals her identity: it is Fátima, one of the Unit’s agents who was being blackmailed to get her to reveal information. Her collaboration enables Nahila to be arrested, but Fennec kills himself to avoid falling into the hands of the police. Al Hassan manages to escape, thanks to the CNI.

Episode 6

Al Hassan has fled, but now that the cell is neutralized the members of the Unit can go back to their lives without police protection. However, they are oblivious to the last part of Al Hassan’s plan, which is still in place: four men attack Lua’s school and take her and some other children hostage. The Spanish authorities refuse to collaborate in locating Al Hassan to put a stop to the attack, so Carla needs to get involved in resolving the hostage situation… and there’s no way of doing it without fatalities.
