It's the beginning of a new era for young Martin Moone: his first day of secondary school, an exciting time as he ventures into a more grown-up world.
While would-be ladies' man Padraic is thrilled to be surrounded by girls, Martin is less than impressed, what with their chat about Patrick Swayze, periods and scrunchies. He soon changes his tune, though, when he meets his new art teacher Miss Tivnan, a vision at the lackboard who sparks romantic rivalry between Martin and Sean.
Elsewhere, Dessie has an important question for Fidelma. He wants to make an honest woman of her and, taking advantage of his position as DJ at the school dance, makes a public declaration of love.
Just as it seems the Moones can't draw any more attention to themselves, Debra encourages Martin to kick-start the dancing. Egged on by Miss Tivnan - who's more concerned with getting her hands on PE teacher Brian - he boldly takes to the floor to throw some shapes, showing that nobody puts Martin Moone in a corner.
