During Holy Week, a ritual sleeping and the disappearance of an American soldier bring together Magaly Castillo and Lucía Gutiérrez to investigate.

While Lucía investigates a new case involving a missing minor, Magaly seeks help in tracing Johnson's off-base activity.

While the search for Samuel intensifies, Lucía joins Magaly and her driver, Sgt. Andrew Taylor, to investigate a lead in Johnson's disappearance.

While María finds a crucial clue in Antonio's online activity, Lucía faces an increasingly complicated home life.

Haunted by his painful past in Montana, Andrew's life is changed forever when he crosses paths with a fellow airman and a Morón resident.

While Lucía inches closer to locating Samuel, Magaly suspects that another military officer may be involved in Johnson's disappearance.

Lucía contends with a loss in her personal life, while Magaly's investigation leads her down a dangerous path.

As the Guardia Civil deploy a search during the procession of Santo Entierro, Lucía and her colleagues race to find a volatile suspect amid the crowded streets of Morón.
