La frontera (2025)

In 1987, France begins collaborating with Spain against ETA, and a dissident ETA cell decides to strike in Paris anyway, rejecting the organization's official decision not to open a second front in France.

Mario Sanz, a young Guardia Civil captain in San Sebastián, intercepts a coded message through a French contact that points to an imminent attack in Paris, and he realizes the threat is real before anyone in his chain of command is willing to act decisively. He reports the warning to his superiors, but the Spanish government chooses not to intervene, calculating that a French attack on French soil will force Paris to cooperate more fully against ETA.

Mario refuses to accept the order to stand down, and he travels secretly to Paris to warn his French counterpart, police officer Léon Renaud, despite their strained relationship and the political risk of disobeying his own authorities. At this stage, Mario is also trying to keep his relationship with Izaskun discreet; she is a young teacher in San Sebastián, and he has not yet fully grasped how closely her life is tied to the world he is investigating.

As the investigation widens, the series reveals that Izaskun is not simply an uninvolved civilian but the daughter of an ETA leader. That revelation changes the stakes immediately: she is linked personally to the terrorist network Mario is trying to stop, and she becomes part of the conflict rather than standing outside it.

The ETA leadership does not want the Paris attack either, but a more radical dissident faction pushes ahead on its own, creating a split inside the organization. Mario, Léon, and Izaskun are then forced into an unstable alliance, because the people actually behind the Paris plot are operating independently and the only way to stop them is for the Spanish captain, the French policeman, and the ETA-connected woman to cooperate.

The dissident terrorists first need explosives, and they turn to the Marseille mafia to get them. Rather than letting the deal happen unchecked, Mario, Léon, and Izaskun choose a dangerous trap: they allow the transfer to proceed so they can identify and capture the terrorists when the explosives are received.

The operation fails to produce an easy arrest, and the terrorists escape with the explosives, leaving the attack still in motion and more dangerous than before. Mario and Léon continue following every lead they can find, and they eventually locate a terrorist safe house, only to discover that the suspects are already gone when they arrive.

With the terrorists disappearing and the deadline closing in, the case enters its final phase as a race against time. Mario, Léon, and Izaskun keep pressing forward under mounting pressure, knowing the attack in Paris is now imminent and that every decision they make could determine whether civilians live or die.

In the end, the three of them continue the chase with the understanding that stopping the bombing now depends entirely on their last efforts, even as the terrorists remain one step ahead.

Short version: the series ends with Mario, Léon, and Izaskun still racing to stop the Paris attack, with the terrorists' plan remaining active and the final outcome unresolved in the available episode summaries.

Expanded version: the ending information available from the episode listings shows the story closing on the final push to stop the attack, not on a neatly confirmed aftermath.

In the last phase of the story, the terrorists have already disappeared, and the attack is described as imminent. Mario, Léon, and Izaskun are still working together under intense pressure, trying to locate the people behind the plot and stop them before the assault can happen. The series' episode guide does not provide a scene-by-scene account of a completed final confrontation, nor does it state that the attack is fully prevented or carried out.

For the main characters at the end, the available sources say the following: Mario Sanz remains active in the effort to prevent the bombing, continuing to act against orders and alongside Léon in France. Léon Renaud is still partnered with Mario as the French police contact working the case. Izaskun is still involved with them and remains part of the effort to stop the attack, after being revealed earlier as the daughter of an ETA leader. The terrorist group's dissident members are still at large at the end of the available summaries, and their attack on Paris is still the central unresolved threat.

Chronologically, the final stretch begins with the group's disappearance. From there, the focus stays on Mario, Léon, and Izaskun pushing forward against the clock. The summaries describe them racing to prevent the attack, but they stop short of detailing a final scene in which the bomb plot is definitively resolved. Because of that, the ending can only be stated as an open-ended, high-tension final movement in which the protagonists are still trying to stop the attack as the story ends.

There is no evidence in the available sources that La Frontera (2025) has a post-credit scene. The results identify the series and its release date, but they do not describe any mid-credits or post-credits footage for it.

If you want, I can also help check whether a specific episode or finale has any extra scene after the end credits.

The central characters are Mario Sanz, a young captain in the Guardia Civil; Léon Renaud, his French police contact; and Izaskun, who becomes Mario's new partner. Mario discovers that a dissident ETA group is planning an attack in Paris, and he works with Léon and Izaskun to stop it. Izaskun is also revealed to be the daughter of an ETA leader, which makes her role especially fraught and personal.

Mario disobeys orders because he believes the attack in Paris is real and urgent, and he decides that warning the French police is more important than obeying the command to ignore it. He secretly goes to Paris to alert Léon Renaud, even though his superiors want him to stand down.

Izaskun is revealed to be the daughter of an ETA leader. That matters because it places her inside the world of the group she is helping to stop, turning her into a character caught between loyalty, family ties, and the need to prevent the Paris attack.

Jon and Ainhoa are the dissident ETA members sent to carry out the operation in Paris. They are responsible for moving the plan forward, including obtaining explosives in Marseille. Ainhoa is also described as fanatical, and one source says she killed one of Mario's colleagues at the border, which intensifies Mario's personal stake in stopping the attack.

The ETA members turn to the Marseille mafia to get the explosives they need for the attack. The authorities allow the handoff to proceed in a risky attempt to catch them in the act, but the operation fails and the terrorists disappear, leaving Mario, Léon, and Izaskun racing against time as the attack remains imminent.

For children or very sensitive viewers, La frontera (2025) is not likely to feel fully family friendly. The available listings identify it as an action/drama/thriller, and even limited content notes point to tense, adult subject matter rather than light or child-oriented material.

Potentially upsetting or objectionable elements may include: - Violence and threat, since the series is described as involving action/thriller elements and border-related conflict. - Language, though the available results do not give a full profanity count for this TV series specifically. - Adult themes, including political and border-related tension that may be heavy for younger viewers. - Emotional intensity, with a serious, dramatic tone rather than a playful or comforting one.

If you meant the 2025 TV series specifically, the search results do not provide a detailed scene-by-scene parental guide, so I can only say that it appears better suited to older teens and adults than to young children.
