Tom Vaughan-Lawlor is set to play the role of a priest in a new RTÉ series alongside a stellar cast.

These Sacred Vows is a comedy drama that will also star Derry Girls star Justine Mitchell, Jason O’Mara from Agents of SHIELD and The Man In The High Castle, and India Mullen from Normal People and  Say Nothing.

Also joining the cast are Irish comedians Shane Daniel Byrne and Catherine Bohart.

These Sacred Vows opens the morning after the wedding, when the body of a priest is found floating face-down in the swimming pool of the young guests’ villa.

Over the course of six episodes, the action jumps back in time to revisit the key events of a wild previous week, each from the perspective of a different character.

Fr. Vincent is played by Tom Vaughan-Lawlor, mother-of-the-bride Sandra by Justine Mitchell, father-of-the-bride Jerry by Jason O’Mara.

David Crean, Acting Head of Drama RTÉ said: “RTÉ is excited to bring John Butler’s brilliant new drama to screen. His story leaps of the page with life and fun and naughtiness and will be such a treat for Irish audiences in what is a big year for RTÉ drama . These Sacred Vows underlines RTÉ’s commitment to showcase the very best of Irish talent and deliver a range of fantastic local drama to audiences in Ireland.”

The show starts production on location in Tenerife on Monday.

These Sacred Vows will air on RTÉ in 2026.
