[REC] 3: Genesis (2012)

Plot: This movie is set in a timeframe prior to the other two 'REC' films. It involves a couple (Clara and Koldo) who are about to be married. All their friends and family are there at the church and some are filming the wedding. Everyone can see that the couple are so in love, so happy, yet so not ready for what is going to happen while at the reception. They notice the police arriving outside the reception hall, but they're not sure on why they are there. And as in the first two films, things turn nasty for all involved. Will the newly weds survive the night?
