The Mainland (S03E04)

What begins as an ordinary journey to the mainland quickly spirals into chaos, with Dougal nearly succumbing to malnutrition, Mrs. Doyle ending up behind bars, and Ted facing a near-fatal altercation with Victor Meldrew. Meanwhile, Father Jack finds himself enrolling in Alcoholics Anonymous. The situation takes a turn for the bizarre when they unexpectedly reunite with old acquaintances Noel Furlong and the St. Luke's Youth Group in some eerie caves, leading to a series of spelunking mishaps for the group.
