Join Hattie and Jo as they head to Southern Ireland to open Boomerville Manor, a holiday retreat for guests of 'a certain age'. There's Irish craic and shenanigans aplenty for the colourful cast of characters as everyone gathers for the grand opening. Meet Melissa, an ex-cabaret singer running from her abusive husband, and Bill, a bachelor bullied from beyond the grave by the ghostly voice of his mother. Along with local bobby Harry the Helmet, ageing aquatic team the Boomerville Babes, eccentric artist Lucinda Gray, and heartthrob Finbar Murphy, they gather in Ireland and the fun begins. But murder is in the air and there's mischief afoot. Will the residents get more than they bargained for at Boomerville?

Set in the beautiful Irish countryside, 'Boomerville at Ballymegille' is a heart-warming story of friends
