It stars Ingrid García Jonsson, Silvia Alonso, Goize Blanco, Nicolás Iloro and Alberto Bang as a group of Spanish friends who travel to Venice as part of a vacation plan, but as soon as they arrive to their destination, they encounter with furious inhabitants who refuse to welcome them, and a deadly killer who hunts each of them down.

[11] Jesús Palacios of Fotogramas rated the film with 4 out of 5 stars, writing that it presents a "schizophrenic exercise in the love of evil, of villains torn between reason and irrational murderous madness, of scapegoats and moral and social dilemmas", praising its boldness while negatively pointing out at its "rather soft" ending.

"[14] Oti Rodríguez Marchante of ABC scored 2 out of 5 stars, assessing that De la Iglesia and Guerricaechevarría managed that their story do not say much, which is what it is all about, and that its characters are tiresome and stupid enough that any violence inflicted on them becomes normal and bearable to the viewer.

[15] Raquel Hernández Luján of HobbyConsolas scored 60 out of 100 points ('acceptable'), deeming the film to be an "imperfect slasher" displaying a message denouncing mass tourism that fails at making viewers empathise with the protagonists.

[16] She praised the opening credits and the transgressive elements blended with the carnival's imagery while considering the production issues not solved at the editing stage to be the worst about the film.
