It is possible you are thinking of:
* "Vera" a British crime drama series that started in 2011, starring Brenda Blethyn as DCI Vera Stanhope. However, there is no episode with that specific title in the show's run.
* Another film or TV show with a similar title that you may be misremembering.
Could you please clarify the title or provide more information so I can help you find the cast you're looking for?
