A perfectly routine trip to the mainland results in Dougal almost dying from malnutrition, Mrs Doyle being chucked in the clink, Ted nearly being beaten up by Victor Meldrew, and Father Jack joining Alcoholics Anonymous. A chance encounter with old friends Noel Furlong and the St. Luke's Youth Group in some spooky caves spells spelaeological trouble for our heroes.
