Love/Hate

After almost losing everything to DI Moynihan's sting operation, Nidge travels to Spain to negotiate with wholesale supplier Terence May for a new drugs shipment. Meanwhile in Dublin his enemies are closing in: Siobhan is acting as informant to Moynihan; Patrick has returned to Dublin determined to kill Nidge; and tensions between Nidge and maverick Fran are reaching boiling point.

With Pauley's help, Nidge is back in business and arrangements are made for the first shipment under the new deal. Meanwhile Moynihan wrestles with a labyrinthine Garda bureaucracy.

Fran is banged up in prison but he and Nidge both still conspire to have each other killed, while Siobhan finds her dangerous drug fuelled double life is spiralling out of control.

Siobhan is increasingly caught between her quest for revenge and her growing love for Pauley - while Nidge may have found a way to get to Fran in prison.

In the aftermath of Pauley's death Siobhan must face her most terrifying opponent yet as Terence May flies in from Spain to lay his nephew to rest - and to find the truth.

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.
