High Tension (2003)

Alexia travels with her friend Marie to spend a couple of days with her family in their farm in the country. They arrive late and are welcomed by Alexia's father. Late that night, a sick, sadistic killer breaks into the farmhouse, slaughters Alexia's family--including their dog--and kidnaps Alexia. Marie hides from the criminal and tries to help terrified, hysterical Alexia, chase the maniac, and disclose his identity in the end.
