The Walsh Sisters: Story, Cast and Series Facts

Story and premise

RTÉ has announced The Walsh Sisters, a new six-part drama series based on celebrated Irish author Marian Keyes' best-selling novels about a chaotic, dysfunctional but deeply loveable family of five sisters, a devout mother and a bemused father. 

Set in their Dublin hometown, The Walsh Sistersfollows the lives of Anna, Rachel, Maggie, Claire and Helen as they navigate the peaks and troughs of their late 20s and 30s. This is a sisterhood full of in-jokes, hand-me-down resentments and more than a few old wounds. But their DNA, history and shared love of power ballads keep the Walsh sisters together in the face of heartbreak, grief, addiction and parenthood.
