After the death of her husband, a grieving widow and a tormented ex-cop investigate a series of murders apparently related to the Universal Expo held in Seville in 1992.
When Amparo's husband is killed in a massive explosion, a strange figurine suggests it was not an accident, so she turns to a haunted ex-cop for help.
Frustrated by police inaction, Amparo travels alone to Seville, where a stranger warns her to stay away while the killer prepares to strike again.
Amparo unravels a 30-year-old blackmail fiasco, revealing a darker side to the Expo. Joined by Richi and Robledo, she searches old archives for clues.
As a explosion harms an unintended victim, Richi and Amparo track down a key player from the Expo, while Robledo teams up with a forensic investigator.
Reeling from yet another tragedy, Amparo and Carmen join forces and look into Rosa's past. A shaken Richi stumbles upon a vital piece of information.
Palacios attempts to buy his safety; but as the killer's bloody vendetta reaches its crescendo, the race to stop him takes a high-speed turn.
