A weekend getaway to the coastal town of Las Rocas turns fatal when the youngest member of a close group of adult friends is found dead on the beach. Prosecutor Guerrero (Soledad Villamil) takes charge of the homicide investigation and begins interrogating each survivor. As the inquiry deepens, every friend presents conflicting versions of events, concealing secret extramarital affairs, romantic jealousies, and hidden betrayals that simmered beneath the surface of their group dynamic. The police procedural unfolds alongside the gradual exposure of personal deceptions, revealing that nearly everyone in the victim's orbit had a motive tied to broken relational trusts.
