Scully is becoming increasingly disillusioned with school, but is enticed by the chance of getting to know Joanna. His afternoon is far more confrontational, as an ill-prepared supply teacher takes over his maths class.
Scully fancies Joanna but Mooey interferes when Scully tries to get to know her better. It's not helped by Marie Morgan, who fancies Scully and tries to fix a date with him. At school his classmates torture a relief teacher who jumps out of the window and Scully follows to avoid the panto.
