The Sacred Family(La sagrada familia)

It's Easter in the beach house of a Chilean well-to-do and nowadays family. A self-centered and successful father, a disoriented mother and a son overshadowed by his successful father. The three of them, wait for the arrival of the son's first official girlfriend; a disturbing and rebellious young lady who will invade the house with her powerful sexual load and other "gifts", breaking loose an emotional cataclysm with no stepping back.
