Filming has begun in Belfast on a new contemporary psychological thriller penned by Derry Girls writer Lisa McGee and her actor-writer husband, Tobias Beer.
The Deceived will tell a "compelling, sinister narrative of lust, manipulation and betrayal", set in both Cambridge in England and Co Donegal.
The central character is English student Ophelia (Emily Reid), who falls in love with her married lecturer, seeing in him all the answers to her needs.
When their affair results in a shocking and tragic death, Ophelia finds herself trapped in a world where she can no longer trust her own mind.
The thriller stars Peaky Blinders actor Emmett J. Scanlan as the timelessly attractive and charismatic English lecturer Dr Michael Callaghan, while Game of Thrones star Ian McElhinney will take on the role of Michael’s father, Hugh, who is fighting the oncoming tide of dementia.
McElhinney previously had a starring role as Granda Joe in the multi-award winning Derry Girls.
Lisa McGee said: “We always had a ‘dream cast’ in mind when we began working on the show, but never imagined we would end up with them actually on board.
"With the brilliant Chloe Thomas directing, we are thrilled to have the story in such gifted hands.”
New Pictures, the production house behind The Missing and Catherine the Great, are making the four-part drama to air on Channel 5 and Virgin Media Television, Ireland in 2020.
The show will represent a return to drama for McGee who has previously created Raw for RTE and written for Being Human and The White Queen on BBC.
Channel 4 commissioned a third season of hit comedy series Derry Girls earlier this year, but according to cast and crew, filming will not begin until 2020.
