Marlin Academy, is an Alabama military school whom Edwin Spangler was a commandant of for the first 2 seasons and beginning of season 3. He ruled the school with an iron fist and hates cadets who disrupts authority with insurrection. Spangler loses his job at Marlin after a cadet reported him to the police about him being drunk and charges were filed against him.
Lois Wilkerson had sent her eldest son, Francis, there after getting arrested for what happened. His insurrection and rebellious nature caused Spangler to clash with him a lot. Francis emancipates himself and leaves school in season 3's Houseboat, with the help of an uncsrupulous, cheap lawyer. This ends up incurring Lois' wrath because she was against him leaving school from the start.
