Apartment concierge Cesar (Luis Tosar) is a miserable person who believes he was born without the ability to be happy. As a result, he decides his mission is to make life hell for everyone around him. A majority of the tenants are easy to agitate, but Clara (Marta Etura) proves to be harder than the most. So Cesar goes to creepy extremes to make this young woman mentally break down. Things get even more complicated in this twisted relationship when her boyfriend, Marcos (Alberto San Juan), shows up.

Wow! This film will creep the hell out of you
8 May 2012 | by (United Kingdom) – See all my reviews

I had no idea what this film was about before I saw it, and boy was I pleasantly surprised. From the same director as REC and also set in an apartment block. This Spanish gem has a great cast, especially the lead 'Luis Tosar' who plays his part superbly, filling you with an ever increasing sense of unease and shock at what you're witnessing. It's very beautifully shot too, making the most of it's apartment block setting. By the end of the film I was left thinking "this could actually happen".

It's by far one of the creepiest, most twisted tales I've had the pleasure of watching in a long time.

Highly recommended!
