Germain (Fabrice Luchini) is the Language Arts teacher and Claude (Ernst Umhauer) is the gifted student. Claude is given an assignment, write about your best friend. Claude writes about a classmate that he is tutoring in math.
While bored with most student's essays, Germain is intrigued with Claude's story - who concludes each page with "to be continued." Each night Germain reads Claude's essay to his hot wife, Jeanne (Kristin Scott Thomas) who treats the tale as a Harriquin Romance bodice ripper.
**In the House** is a story within a story. Character perception shifts every five minutes. One is not certain if Claude's experiences **In the House** are teen fantasy or potential criminal activity, which raises boundary issues between a teacher and his apt pupil.
