However, after an initially warm welcome, tensions soon boil over when it's discovered that Barry has unexpectedly been left half the money in Ciarán's father's will. With the two men now torn apart by greed and jealousy, resulting in a feud that spirals into a series of pretty squabbles and disastrous hijinks, will they ever be able to give peace a chance again?
