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.
