London: 1963. The lives of a professional shoplifter and a young art student collide. Delia needs to atone for a terrible mistake; Tess is desperate to convince herself she really is an artist.

Elsewhere in London, the Krays are on the rise and a gang war is in the offing.

Tess’s relationship with her gay best friend grows unexpectedly complicated, and Delia falls for a man she’s been paid to betray. At last, the two women find a resolution together - a performance that is both Delia’s goodbye to crime and Tess’s one genuine work of art.
