Second series of the hard-hitting Irish drama set in Dublin's drug-riddled gangland. Darren (Robert Sheehan), recovering from a gunshot wound, remains unable to escape the clutches of powerful drug overlord John Boy (Aidan Gillen). Darren's love for Rosie (Ruth Negga) once again holds him in place long enough to become embroiled in John Boy's world. Worse still, the drug leader's dispute with rival Fran (Peter Coonan) sees him become increasingly erratic and dangerous. Darren will have to tread extremely carefully if he is to remain in one piece.
