The captivating reality series will be recorded on site in Ireland and will feature candidates from all around the country, following in the footsteps of its award-winning counterparts in the US, UK, and the Netherlands.

Earlier this year, a worldwide casting call brought together a wide range of players for the ultimate test of loyalty and treachery.

Steve Carson, the Director of Video at RTÉ, commended McSweeney's skill. "Siobhán is a very talented actor with a great range of comedy and drama.”

“We are confident that she will contribute something very unique to Ireland's rendition of this wonderful game of trickery and trust."


The psychological reality show, which is produced by Kite Entertainment, pits 22 strangers against one another in a game of strategy, betrayal, and trust that takes place inside a castle.

With €50,000 on the line, competitors must complete daily missions to increase the reward fund while identifying the traitors and eradicating them one by one.

A Traitor will keep the money if they are not caught, but survivors who make it to the final will have the opportunity to claim the prize.

In 2025, RTÉ One and RTÉ Player will broadcast The Traitors Ireland.
