Last week, we posted about what's new on BritBox in September, and now, we have the details on Acorn TV, too. As we saw with BritBox (and with past years), things are starting to pick up in September – something that always happens around the time cooler weather is on the way. As far as we're concerned, the best thing on the upcoming schedule is the premiere of Murder Before Evensong, but it's far from the only thing coming. Full details and descriptions await below…

Shows Continuing on Acorn TV in September 2025

Irish Blood (2025)

In this six-part mystery drama, Fiona (Alicia Silverstone, Clueless) is a high-powered lawyer whose tough exterior was forged by a childhood betrayal—her father, Declan (Jason O’Mara, The Man in the High Castle), walked out on her and her mother on her tenth birthday, never to return. Or so she believed.

When an unexpected message draws her to Ireland, Fiona is forced to confront the truth about the man she’s spent her life resenting. What she uncovers is a family who never knew she existed and a buried past wrapped in secrecy, deception, and criminal ties.
