The fiction is set in Tramuntana, a fictional village in the Serra de Tramuntana mountain range,[1] in the Mediterranean island of Mallorca. The events take place a year after the solving of the case of the girls of Monteperdido,[2] in which agents Sara Campos and Víctor Gamero took part.
The plot starts with the murder of Bernat Cervera. Sara Campos assumes the investigation, partnering with Gamero.[3] She also has to deal with Sgt. Selva, a cocky and overbearing agent.[3] But as the case is solved and the murderer is identified, new questions arise.[4]
Produced by RTVE in collaboration with DLO Producciones,[6] and written by Agustín Martínez (the creator of Monteperdido) together with Miguel Sáez Carral, Jorge Díaz and Antonio Mercero, the series was directed by David Ulloa and Rafael Montesinos.[2] The village of Valldemosa in the island of Mallorca was used to portray the fictional village of Tramuntana where most of the plot takes place.[1] Other shooting locations included the port of Sóller, the lighthouse of Sóller, Cala Tuent, Port des Canonge, Mirador de s´Entreforc, Cala Pi [ca], Andratx, Llucmajor and Esporles.[1] Interrupted for three months because of the COVID-19 lockdown, shooting of the series resumed by July 2020.[7]
The first episode of the series premiered on 13 January 2021 on La 1 with an unimpressive 8.0% audience share and 1.3 million viewers, far from the figures of its predecessor, Monteperdido.[8] The series fared comparatively better with online catch-up reproductions than with linear TV, adding 540,000 weekly viewers to the total.[9] The broadcasting run of the 8-episode series ended on 3 March 2021.[10]
