Miss Gulliver is peeved when she is not allowed to give the drugs awareness lecture, that job going to the ultra-trendy India, who actually takes drugs herself. Anxious to impress India Alfie invites her to a rave but, learning that no pupil has any drugs to sell, makes his own. This has a disastrous effect, leading him to believe he is the Little Mermaid. Professor Green calls the police and Stephen's parents arrive to take him out of the school. Fortunately Miss Gulliver saves the day by persuading everybody that Alfie was taking part in a very realistic anti-drugs role play.
