This third entry in the "Carry On" sweepstakes concerns William Wakefield (Ted Ray), the much-loved headmaster at a British school, who applies for a new job at a recently built country school. When Felicity Wheeler (Rosalind Knight) and Alistair Grigg (Leslie Phillips) from the Ministry of Education come to the school to check out Wakefield's qualifications, the students, not wanting their headmaster to leave, disrupt the school procedures to sabotage Wakefield's job application. Their subversive behavior comes to a head during a school production of Romeo and Juliet which degenerates into a free-for-all where it becomes every educator and student for him or her self.
