This time Timothy joins his brother-in-law's driving school. The school is soon in rivalry with a competing school, whilst Timothy finds himself in erotic adventures with his landlady and clients. His clients are a mix of the inept and the dangerous. As usual, mayhem ensues. A rugby match is organised between the schools, only to see an opponent unknowingly swallow a Spanish Fly and rampage around the field, leading to the climactic car chase.
