A terrorist bombing in downtown Bilbao kills seven and wounds dozens, wracking havoc in its wake. A young Muslim, Omar, is kidnapped and framed for it.

Gorka, one of the bombing victims, is eulogized by brother Gaizka, who has ties to the bombers. Omar escapes from his captors and is chased by the cops.

Edurne, Omar's girlfriend, teams up with Juan, a journalist, to try to prove his innocence. Omar is once more kidnapped when he tries to surrender.

Omar manages to get away and makes it to Madrid while Edurne, waiting for his surrender, is arrested as a collaborator.

Edurne is freed to bait Omar. Police investigator Olaegi begins to suspect that intelligence agent Gorostiza is hiding something. Juan gathers clues.

While Omar and Edurne meet, Juan begins to put the larger picture together. Gaizka barely keeps a grip on his company and a step ahead of Gorostiza.

Edurne and Omar arrange to flee Spain. Juan hits on proof that exculpates Omar. Gorostiza tries to recruit Olaegi, while her suspicions about him grow.
