The Betrayed: Episode 1. Siblings

A five-part drama about a family - and a society - divided by far-right populist extremism.

When Louise a senior officer in the Garda Síochána sees her brother Frank on the news, taking part in an aggressive far-right protest she is shocked. Not least because she is and she had no idea Frank had been influenced by the populist extremists who hurl accusations of being 'traitors' at police and politicians alike.

In the aftermath, Frank's face doesn't show up on CCTV. But when she threatens to have him arrested, he accepts the deal she reluctantly offers - she will cover for him if he promises to stay away from demos and protests.

But then Louise learns that Frank is connected to a much wider network. He's in touch with organised extremists throughout Europe, Louise realises that Frank is on a path that could bring Ireland, and other countries, to the brink of chaos. The time has come to break up his network, whatever the family consequences.
