Actor Vicky McClure shares her determination to shine a light on dementia

Line of Duty star Vicky McClure introduces us to her Dementia Choir, subject of a third series on BBC1 this autumn.

Vicky also reveals how she uses music to help her prepare for roles in dramas like Trigger Point; chats about an incredible decade in Line of Duty, and the first film she's made with her production company -  Build Your Own Films - in her home town of Nottingham.
