The post-pandemic era caused a spread of express kidnappings in Spain. Criminal psychologist Barbara Vazquez begins working for Zentral Risk and recruits a peculiar team to solve these crimes.

After the discovery of the body of a gang member, the police suspect they are facing something more dangerous. After crossing many red lines in her first case, Barbara resigns to focus on her family.

After an event at the container warehouse, Barbara decides to stay at the head of the Express Team. The Commissioner no longer believes Latin gangs are causing the wave of kidnappings.

Santa's suspicions of Barbara continue. He puts a microphone on Roldan and listens to how the Express Team recognizes its involvement in the container warehouse event. The circle is closing.

Zentral Risk prepares its IPO. Meanwhile, Team Express receives a new case; the rescue of Triana's stepfather. Barbara discovers that the one on the other end of the phone is her own daughter.
