A sleepy Irish fishing community is destabilised by the return of Brian (Paul Mescal), the errant son of Aileen O’Hara (Emily Watson), who shows up unexpectedly at the funeral for a local fisherman, announcing his intention to revive his brother-in-law’s defunct oyster farm. Aileen’s husband, Con (Declan Conlon), has become estranged during Brian’s extended absence, and her relationship with adult daughter Erin (Toni O’Rourke), a new mother, isn’t as warm as it ought to be. While Aileen welcomes Brian with open arms, not everyone in the family or community does, in particular his ex-girlfriend, Sarah (Aisling Franciosi), who broke his heart years ago. For Aileen, Brian’s return is a beacon of light and hope in her otherwise stifled existence, but her unfailing loyalty to her son is soon tested when sinister allegations about him begin to surface.
