In the final episode of the series, Grayson looks at 21st-century tribes. We live in an age in which everyone proclaims their individuality, but as he meets his subjects, Grayson discovers that the urge to band together with like-minded souls is as strong as ever.
In Belfast, Grayson meets five Loyalists, who take part in a march to commemorate the founding of the Ulster Volunteer Force. Grayson's portrait both borrows from and subverts the militaristic imagery of Belfast's murals and the marchers' banners.
Next Grayson meets contestants in the Miss Plus Size International competition, exploring how a struggle for acceptance has shaped their identity, and drawing on classical sculpture and ancient fertility symbols in his portrait.
Finally, Grayson meets a group of deaf people who see their deafness not as a disability but as an enriching and rewarding identity. In the final scene, Grayson invites the sitters to the National Portrait Gallery, where he reveals the portraits to them for the first time.
