REC 3: Genesis (2012)

Koldo and Clara are about to celebrate their wedding day and have gathered their friends and family in a sumptuous country house for the occasion. That evening, a veterinarian recently bitten by a dog develops abnormal behavior and becomes aggressive. In a few moments, an uncontrollable wave of violence sweeps over the party as an increasing number of guests are infected as a result of bites. Clara and Koldo are separated amidst the chaos. Koldo finds refuge in the kitchen with his cousin Adrián, Clara's sister Tita, the wedding photographer Atun and a copyright inspector nicknamed "Royalties". They escape through the air-conditioning ducts, apart from Atun due to his size. Outside, the group finds a police vehicle and a guest eating the policeman's flesh. After killing her, they try to contact the police, but Royalties is devoured by the now-infected policeman. The vehicle's sirens are triggered and alert the infected. The group escapes and joins other survivors within a chapel, which the infected cannot enter. Through the P.A. system, Koldo hears Clara say that she is safe as well as pregnant, and he decides to find her.

Clara and the wedding priest have found refuge in the video surveillance room and are helplessly watching the carnage unfold. Spotted by the infected, they escape and find Rafa, a friend of the couple, and Natalie, Clara's French friend who had retired to a room for sexual intercourse without realizing the situation. Clara, Rafa and Natalie flee while the priest immobilizes the infected by reciting a prayer. Meanwhile, Koldo arrives at the surveillance room and witnesses the massacre of Adrian, Tita, his grandmother, and others as they get cornered and eaten by the infected. Clara, Natalie and Rafa meet another survivor, children's entertainer "Sponge John". Natalie is bitten and Clara faces her infected mother. John shoots the mother before he himself is bitten. Clara and Rafa flee through a tunnel, but Clara turns around when she hears a song played by Koldo in the ballroom.

Clara, followed by Rafa, takes a chainsaw and fights her way through the infected, but Rafa is bitten and Clara is forced to kill him. Koldo enters the kitchen to find a dead Atun, having slit his wrists to prevent infection, and killing the Vet with a kitchen tool. Clara finds Koldo in the kitchen and both are surrounded by a horde of infected, which are suddenly paralyzed by the voice of the priest reciting scripture over the P.A. system. Clara and Koldo go out into the garden, where Clara is bitten by Koldo’s infected grandfather, whose deafness renders him immune to the prayer. Koldo cuts Clara's arm just below the elbow to stop the infection and they arrive at the estate's exit, where they discover that the authorities have quarantined the area. The attempt to stop Clara's infection fails and she begins to show signs of turning. Koldo takes her outside where the police and a GEO team tell him to let her go. Clara and Koldo share a final kiss before Clara, now fully turned, bites his tongue off and then turns to attack the armed men who shoot both of them down. Clara and Koldo hold each other's hands as they die from their gun wounds.
