As both Dano and the Gardaí begin to put the puzzle together, what can Nidge do to stay ahead and stay alive?

Pressure builds on Nidge as the leaders of Dano’s organisation send an inquisitor down from the north to thwart him, and matters only get worse as his lies start to catch up with him.

Nidge struggles to allay Dano’s suspicions when his secret threatens to get out as Siobhan and Elmo, for different reasons, start to talk.

Nidge sets out to persuade Dano that he had nothing to do with his father’s disappearance but a scapegoat must be found. Nidge turns to ever faithful Darren for help.

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.

Nidge swiftly fills the power vacuum and gets the gang back to business as usual. Rosie has realised what her lover has become, and Darren is devastated when she breaks up with him. Meanwhile Mary finally realises the extent of Luke’s psychosis as she finds him lurking in her bedroom at night.

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. Paranoid John Boy finally tips over the edge of sanity when he finds Debbie taking heroin.

The crew are in festive spirits as Trish has the baby on Christmas Eve, while Rosie has come back to Dublin and Darren falls in love with her all over again. However the gang war is still raging, and John Boy orders Tommy – already caught between his friendship with Debbie and his worries about Siobhan’s money runs – to kill Fran. The hit goes wrong, and someone else becomes fatally caught up in the aftermath.

When a container of drugs is busted at the docks, John Boy decides to double cross Fran on their deal. Fran retaliates against John Boy. John Boy is furious and orders Nidge to pipe bomb Fran’s house leaving Fran determined that the escalating gang war will not end until he has revenge.

Disaster strikes the gang as a drug mixing factory is busted by the gardai. John Boy blames Stumpy who he believes sold them out. Darren, desperate to get out of the game, robs an ATM machine and makes a downpayment to John Boy against the debt he owes. John Boy, however, wants Stumpy taken care of and he wants Darren to be the one to deal with it.

In debt to loan shark Fran, gang footsoldier Darren finds he has no choice other than to turn back to his former mentor, northside kingpin John Boy Power. Under pressure from the cops and doing way too much cocaine, John Boy is becoming paranoid and erratic. John Boy agrees to take on Darren’s debt in return for absolute loyalty – the deal with the Devil done, Darren is back on the team…

As Nidge and Trish’s wedding day arrives, gangwar is breaking out. John Boy and Hughie generate new plans and new recruits. Who will be with them?

Darren is worried about John Boy and Hughie’s volatility, not just for himself but for his sister Mary and the kids. Relations between John Boy and Darren come to a head. Darren decides that it is in everyone’s interest that he heads for London. Can he end the war before he leaves?

The gang come back from Nidge’s stag party in Prague to learn that Jimmy Byrne is back in town. His friends think Darren should kill him as soon as, but Darren’s not so sure. Tension mounts as Darren needs to make decisions not only about whether to follow through on his suspicions, but about what he should do about his feelings for childhood sweetheart Rosie.

As Darren grows closer to uncovering the truth, tensions and suspicions rise among the gang. Darren in particular faces difficult decisions about his feelings for Rosie, his future and his loyalties.

Darren is tracking Jimmy Byrne, the chief suspect in the gangland killing. But in the meantime he needs to work and he soon finds himself slipping back into working for gangland boss John Boy Power. In a world of paranoia and betrayal will Darren be able to keep his wits about him, kill Jimmy Byrne and find love again with Rosie?

Darren Tracey skipped Dublin when a gun was found in his house and he’s been living the past year in Spain, but he decides to risk it and come back to Dublin. He’s homesick and a party for his brother’s release from prison is the perfect excuse. It’s only for the weekend but sometimes life is full of surprises – especially if you and your friends are in gangland.

As the outside world threatens to close in, will James and Alyssa make it as a couple?

James and Alyssa make it to her father’s place. But after the initial euphoria, cracks begin to show.

Excited to be reunited, Alyssa and James get back on the road, where their outlaw status is put to the test.

James and Alyssa arrive at a rundown town. James is unable to block out a memory from his past.

In the fallout of their terrible act, real cracks begin to appear between James and Alyssa.

Alyssa and James decide to lie low, but their hideaway turns out not to be as safe as it first appears.

Alyssa and James hit the road with a bang, but they soon realise how little they know each other.

James is a loner who doesn’t engage with other people. His world is one of violent inner fantasies. No one talks to him at school, and he’s happy with that. But everything changes in an instant when new girl Alyssa accosts him in the canteen… Alyssa is teenage angst made flesh. She feels estranged from her mum; hates her stepdad; and rejects pretty much everyone she meets. That is until she sees James sitting alone one day… Alyssa sees a kindred spirit in James – just as he identifies her as a potential victim. And so their journey begins…
