Grayson Perry explores identity and portraiture, spending time with people facing a crossroads or a crisis about their identity, and making portraits to reveal the truths about who we are. Part psychologist and part detective, Grayson hunts for clues to the sitter's inner life and distils them into a single representation, from miniatures to large tapestries, statues and pots. This episode looks at modern families. Grayson is interested in how powerful and attractive the idea of family remains in a world where break-ups are commonplace, and where we've become used to family units that follow a pattern radically different to the mum, dad and 2.4 kids of the past. Grayson meets a group who might at first seem to stretch the definition of family to its limit, but whose life together is as familial as many more conventional households: the Jesus Army. He then meets Jack and John, white male gay parents who have adopted mixed-race Shea and are conscious both of their own identities and of the need to nurture Shea's. Finally, Christopher was diagnosed with Alzheimer's several years ago and is now looked after by his wife Veronica. Grayson is keen to explore what happens to our identity when memory is stripped away and to relationships when the memories that hold families together disappear.©Channel Four Publicity.
