DJ  and musician Graham Harrison has to cure The Plague befalling Craggy  Island, as the whole place is coming down with rabbits and Ted and  Dougal desperately search for a ways to get rid of them - on the eve of  Bishop Brennan's impromptu visit! Mrs Doyle puts her mechanic skills to  use on Len's car, while Jack confuses his rodents. 

Also  in the Sermon, we try to imagine the Islanders as characters on Police  Academy, rabbit stories - cute AND creepy, which fictional serial killer  Tom is most like and did Father Ted invent a horror trope? It's just a  bad dream, Your Grace.
