Roisin (Hilary Reynolds) and Septa (Maeve Germaine) are two young nurses from Dublin who go to work at a hospital in Belfast. Roisin meets and falls in love with Tom (Dan Gordon), a young Protestant car mechanic. This causes a series of problems for the young couple, their families and friends.
The holiday is soon and Dermot can't go so Septa has to find somebody to take his place.
Alex gets Tom involved in fixing 'dodgy' cars for a local gangster.
Tom's father lends him the money to pay for the holiday. Alex starts a new job in the pub but he isn't quite up to standards.
Alex says he can't go on holiday as his dog is ill and he won't leave it until he makes sure it's ok.
Tom, Alex, Roisin and Septa set off on Holiday to Wales.
