Episode 6 Nidge is summoned back to Spain, where Terence demands a terrible price for his continued support, while Siobhan and Moynihan reach an unholy deal of their own.
Fearful of Dano's revenge, Nidge has moved the family out to a hotel. He reconciles with Darren, paying him a proportion of the money he owes, as his old friend - still on the run - plans to leave the country imminently.
When one of his gang is mistakenly shot by a rival organisation, Nidge plays the diplomat but a mad drunken Paddy's night slides out of control towards disaster.
The police finally put the jigsaw pieces together and the net closes in on Nidge as he finds himself caught between the cops on one hand and a vengeful Dano on the other.
As tensions come to a head the gang threatens to implode: Luke's obsession with Mary is becoming more dangerous, while Siobhan's panic attack at the airport could get Tommy killed. John Boy finds Debbie taking heroin.
