Hollywood TV Exec Wendy Patterson returns to Irish border town Drumbán after 20 years to choose the final filming location for her big budget TV show ‘I AM CELT'. But Wendy shares a decades-old secret with Séamus Proctor, the respectable local doctor and family man, and he'll do anything to keep it hidden. Wendy's tired of being kept in the dark and won't stop until Séamus admits what happened to them in the woods on the eve of the Millennium.
Wendy's return puts Séamus on edge as she tries to commandeer his home for production, and his daughter Joanne's impressive audition for ‘I AM CELT' draws his family further into Wendy's orbit. Meanwhile, Wendy's choice for leading man goes AWOL, setting off a casting crisis, while Séamus realises he can't hide from Wendy forever.
It's Joanne's 18th birthday and the first day of filming for ‘I AM CELT'. Emotions and expectations are running high across Drumbán. When disaster strikes on set, Wendy comes face to face with the other ghosts of her past – her parents, the Reverend and stepmum, Maude Patterson. Joanne's birthday plans scare Séamus into opening up about his past.
Séamus' surgery is busier than ever after his shocking cosmic confession at the White Ridge, but the concerns his patients have are out of this world. Wendy navigates an awkward day on set as Big Jim struggles with unexpected script changes introduced by eccentric showrunner, Jack E. McCarthy. Tensions rise as Séamus' family demands answers, and Wendy drops a bombshell about Catherine.
A legal crisis that puts ‘I AM CELT' in jeopardy forces Wendy, Jules and Jack E. to travel abroad, while Séamus faces a disciplinary hearing and the truth about his marriage. The community mourns a local loss, and mysteries deepen at the Celtic site Oldgrange.
Wendy returns to Drumbán for the local premiere of ‘I AM CELT'. As the town gathers in excitement, outside, Séamus, Wendy, Pubba, Catherine, Shelly and Big Jim return to the woods to confront their pasts and face an uncertain future.
