Plot

Miguel, a young man with a horribly disfigured face, attempts to trick a girl into sex by putting a mask on and pretending to be her boyfriend. When she unmasks him, he brutally stabs the young woman with a pair of scissors. After the crimes, Miguel is institutionalized at a mental asylum for five years. When his sentence is finished, he is released into the care of his sister, Manuela. Along with their invalid aunt and countess Maria Gonzales, his incestuous sister Manuela operates a boarding school for young women called Europe's International Youth-Club Boarding School of Languages on the Spanish resort of Costa Del Sol.
