Derry Girls begins its third and final season tonight as the gang head towards their GCSE results - and the Good Friday Agreement.

The Channel 4 sitcom sets the friendship of a group of teens in the 90s against the backdrop of the Troubles and the series end was always planned to coincide with the peace treaty.

Also back is Siobhan McSweeney as nun headteacher and the group's nemesis Sister Michael, Tommy Tiernan as Erin's dad Gerry, Tara Lynne O'Neill as Erin's mum Mary, Ian McElhinney as Granda Joe, and Kathy Kiera Clarke as Aunt Sarah.

Bridgerton star Coughlan, who plays Clare, said: "It was so life changing for all of us. It was a job I got when I was 30. I didn’t know if I was going to ever have a career doing what I love doing, so that’s a privilege on its own.

"The final season is really a love letter to the fans of the show. That’s why, even after three years, we all fought so hard to get back on set and do this one last time. And I hope we’ve done them proud."

McSweeny, who recently starred in the adaptation of Graham Norton's novel Holding, agreed: "It’s changed my life, this experience, in so many ways. I will never not be Sister Michael. If I’m ever spoken about it will be, 'Oh, she was the nun in Derry Girls.'

"So that has changed my actual bones, my actual identity. I’ve never worked on anything for such a long period of time, and got to work on a character, and revisit a character. That’s so rare in our industry, so that was wonderful."

The girls (and The Wee English Fella) are on the eve of their GCSE results as the series opens, and no one has less faith in them than Sister Michael.

But panicking about their academic future isn't the only thing on their minds as they're also still desperately battling to appear cool at house parties and school alike.

Although few plot details have been released, Coughlan hinted: "There’s a big storyline for Clare this time that I can’t talk about, but (writer) Lisa (McGee) called me a couple of years ago to make sure I was comfortable with it."

We know that the series end coincides with the Good Friday Agreement and McSweeney suggested that there was set to be a sobering finale to the comedy.

She said: "Oh, my God, there should be content warning: This is going to break your heart. Lisa (McGee) has gone full throttle, no tear ducts left standing.

"Our audience will be broken after this. And that’s exactly what they should be, because it’s the final, and it’s a story that deserves to have you broken at the end. Only comedy can break you open that way.

"You’re in for such a treat. Seriously. That finale, you’re going to be broken."

Derry Girls season three begins tonight at 9.15pm on Channel 4.
