S5·E1 Two Flew Over the Cuckoo's Nest

It is still the night of the bonfire party. Niamh decides she must tell Ambrose that the marriage is over. The next day, Niamh leaves Kieran with Siobhan and spends the day with Sean at the lake, and they discuss their future. Sean tells her that he loves her. Meanwhile, Ambrose goes for a walk while engrossed in thought about his troubled marriage when he sees two people in difficulty on the rocks below. He shouts to tell them that he will try to find a way for them to escape the incoming tide. Elsewhere, a Frenchman called D'Argan, has come to challenge ""the head man of the village"" to a balloon race. Donal and Liam go to find Brian who is the closets they can think of. Brian is uninterested until he discovers that the event is to complete a race started 200 years previously, and that £40,000 is at stake. However, Monsieur D'Argan has forgotten that the French economy has had one major change since Napoleonic times.
