When Rose, Carrie and Oscar are captured by the Grandmistress, Frank is determined to rescue them. Using an invention called `Smart Ease', invented to dramatically speed up agent training, Frank turns three more St Hope's pupils into MI9 agents.

The staff and students of St Hope's are left under the Grand Master's control after they are hypnotised by a colourful pattern during a rare solar eclipse. Frank, Oscar and Carrie and even Mrs King manage to escape the hypnosis - but Rose is caught in its spell. Whilst the spies search for answers, the Grand Master launches stage two of his plan: broadcasting the image on every TV in the UK.
