Sara, Sam and friends are putting on a play - what could be more harmless than? It's going to be a nice, restful, fun day to round off the summer term. But this is Freekham High and something unexpected always happens...This time, it's a plague of Pigeons! It's almost as if the birds are deliberately targeting the school, flying into windows and making a mess everywhere...Soon some of the teachers start to get in a flap. Then the costumes for the play start to go missing and Fido threatens to fly off the handle. Everything's going wrong - can they somehow wing it - or will everything end in disaster?
