The Olivier-award winning actress stars opposite Tom Hughes (Victoria, The Game) in the drama which explores the impact of a one-night stand on a young Chemistry teacher’s life with a good-looking but dangerous ducker and diver.
There is an instant, animalistic, spark of attraction before they become locked in a dance of mutual destruction. Only one can survive, but their actions will take a terrifying toll on all those around them.
Speaking last year, Gough said: “Having worked with Conor McPherson on stage I am so excited to work with him again on this amazing project.
“He’s written a script that I know all of us involved feel very privileged to be part of bringing to life. Paula is a brilliantly complex woman and I can’t wait to play her.”
Writer Conor McPherson added: “It’s a great pleasure to work with the BBC and Cuba Pictures on this series.
“Exploring new ways to tell stories is always an inspiring challenge and the opportunity to weave a drama across three evenings is one I have enjoyed immensely.
“The trust and freedom they have given me at every step is something every writer dreams about and the astonishing cast they have assembled couldn’t be more exciting.”
Filming began in Belfast in October.
