First look at new RTÉ comedy-drama These Sacred Vows 

Series coming in 2026 stars Tom Vaughan-Lawlor, Justine Mitchell and Jason O’Mara released today 

RTÉ today released first look images of new comedy-drama series These Sacred Vows. The series, written and directed by award-winning Irish screenwriter John Butler, stars Tom Vaughan-Lawlor, Justine Mitchell and Jason O’Mara and will debut on RTÉ One and RTÉ Player next year.

These Sacred Vows opens the morning after an Irish wedding on a Spanish island, 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.

Today’s photos give a taste of the drama filmed on location in Tenerife earlier this year with a stellar Irish cast including Tom Vaughan-Lawlor as Fr. Vincent, mother-of-the-bride Sandra played by Justine Mitchell, Jason O’Mara father-of-the-bride Jerry and India Mullen as wedding party guest Ava. The ensemble cast also includes Adam John Richardson, Tom Hanson, Aoife Hinds, Shane Daniel Byrne and Catherine Bohart and many more.

Executive Producers of These Sacred Vows are RTÉ’s Head of Drama David Crean and RTÉ’s Director of Acquisitions and Co-Productions Dermot Horan; Rob Walpole and Rebecca O’Flanagan for Treasure Entertainment; Cathy Payne and Simon Cox for Banijay Rights and Kate McColgan for Fís Éireann/Screen Ireland.

These Sacred Vows is one of nine drama productions for RTÉ filmed this year creating 142 hours of high-quality, homegrown storytelling across screens in Ireland. These series are part of RTÉ’s commitment to great local drama.
