As it had happened before, a body appears on the first night of the Carnival. The locals are sure this the work of "Urco", and that more murders will follow until the festival is over.

Mist thick with Galician folklore turns a coastal Carnival into a claustrophobic hunting ground where ancient superstitions clash with modern crime. Local legends of a monster named Urco transform a routine investigation into a frantic race against the rhythm of the festival.
