Break Out Pictures have shared the official trailer for the upcoming film Ballywalter – set to be released in Irish and UK cinemas on September 22.

Ballywalter – Prasanna Puwanarajah's directorial film debut – stars new Late Late Show presenter Patrick Kielty in his first dramatic role, alongside Seána Kerslake, known for her roles in Can't Cope, Won't Cope and A Date For Mad Mary.

"Ballywalter is a life-affirming story about the unexpected connections that can change the course of our lives," the trailer's description on Break Out Pictures' YouTube channel reads. "Eileen (Seána Kerslake) is a caustic, unrepentant University dropout whose dreams of a successful life in London have fallen by the wayside. Back at home with her mum, she makes ends meet by working as an unlicensed driver in her ex-boyfriend’s minicab.

"Shane (Patrick Kielty) has exiled himself in Ballywalter following the break-up of his marriage, but now he’s trying to get his life back on track by enrolling in a stand-up comedy course. When Shane calls a taxi to get him to his classes, Eileen answers and a surprising connection is made. As the two spend time together shuttling back and forth, a beautiful friendship develops, leading both to a moment of realisation.

"Shane reintegrates; Eileen makes peace with herself and who she really is. Finally, she can stop running and just drive."

The film, written by Stacey Gregg, also stars Conor MacNeill, Joanne Crawford and Paul Mallon. It will feature music composed and performed by N.C. Lawlor.

Seána was nominated for Lead Actress (Film) at this year's IFTAs for her role in Ballywalter.
