Pleskit's new in school. He's also purple, bald and has a single stalk growing out of the top of his head. It's going to be an interesting first year . . .
It's the end of the school year - and possibly the end of the alien classmate. Rumours are sweeping Earth about events at the alien embassy, new anti-alien demonstrations have sprung up and Tim and Rafaella have discovered there's a traitor at the embassy. The planet is at stake, lives are on the line - and Pleskit's gone missing . . .
