In 2026, Penny O'Rourke, a former Manic Vibes Liverpool presenter, is abruptly sacked as part of Manic Radio's corporate purge under new CEO Ralph Bernard. Now unemployed, broke, and stuck in Belfast with her husband Weston and their four-month-old son Alfie, Penny struggles to adjust to life outside of radio. As she battles financial instability, a messy co-parenting dynamic with her ex James Smith, and her own self-destructive tendencies, she searches for a way forward. Desperate for income, Penny applies for Universal Credit, explores unorthodox job opportunities, and leans on her former co-host Rory Carter, who was also axed in the purge. But old habits die hard-when frustration and desperation set in, she turns to alcohol, reckless decisions, and past vices. With her career in tatters and personal life spiraling, Penny must decide whether to rebuild from scratch or let her past define her future. A sharp, darkly comedic, and unfiltered exploration of the chaos that comes when your dreams collapse, The Wirral Gal... now a Mam is a gritty, real look at life after the spotlight fades.
