The second season of the popular crime drama series is on the way later this month on RTÉ One. The returning cast for season two includes Charlie Cox as Michael, as Amanda, Aidan Gillen as Frank, Sam Keeley as Viking, Emmett J. Scanlan as Jimmy, Maria Doyle Kennedy as Birdy, and Yasmin Seky as Nikita. Ciarán Hinds as rival gang leader Eamon Cunningham will naturally not be back, for reasons that will be clear to those who’ve watched the debut season.
