The world's most boring priest comes to stay, and he just won't go away. After his worst ever birthday party, Father Ted prays for deliverance from Father Stone, but a lightning strike wasn't what he expected.

Ted goes on a picnic, Mr Benson's whistle is stolen and Dougal learns an important lesson about true friendship. Ted narrowly avoids incriminating himself to save Dougal's worthless hide

Rabbit-phobic Bishop Brennan pays a visit to investigate reports of Father Jack sleepwalking naked. Unfortunately Dougal has overrun the house with rabbits, and a Terry & June-style farce ensues as Ted and Dougal attempt to keep Father Jack in bed, and the ever-multiplying rabbits away from the bishop.

Ted and Dougal turn detective to discover who's behind the bumper crop of hairy babies on Craggy Island. However when justice is done on the culprit he takes a terrible revenge. Dougal's moonlighting stint as island milkman is marred by a bomb set to go off if the milk float drops below 4 mph. Does 'The Poseidon Adventure' hold the key to his rescue, or would Father Jack's pet brick come in more useful?
