In 1993, 16-year-old Brandon Lee enrolled at Bearsden Academy, a secondary school in a well-to-do suburb of Glasgow, Scotland. What followed over the next two years would become the stuff of legend. Brandon had been privately tutored in Canada while he accompanied his mother, an opera diva, on tour before her tragic death. The preternaturally bright student surprised teachers by blazing toward his goal of entering medical school, displaying a wealth of knowledge beyond his years. Brandon found friends despite his initial awkwardness. He took bullied students under his wing, introduced classmates to seminal retro bands, and even starred in the school's production of South Pacific. But then his unbelievable secret was revealed.

Filmmaker Jono McLeod returns to his old school for a nostalgic look at the strange but true story of his former classmate, Brandon Lee. Utilizing playful, period-specific animation, a pitch-perfect soundtrack, the memories of students and teachers, and the talents of Alan Cumming to bring the tale to life, My Old School offers more than one surprise along the way.
