A play of two voices for one actor, about memory, catastrophe and sacrifice. Bríd's coming home to convalesce after drying out in rehab. Ciara's headed west too, investigating a potential archaeological site on a parched area of bogland. But as the countryside swelters in a heatwave, the pair find peace elusive. How will Bríd cope in her old haunts? How will Ciara confront a past she thought forgotten? And will they unearth the hidden truth that binds them together? John O'Donovan's play Sink premiered at the Dublin Fringe Festival in 2019, directed by Thomas Martin.
