Gray Matters explores the long, fascinating life and complicated career of architect and designer Eileen Gray, whose uncompromising vision defined and defied the practice of modernism in decoration, design and architecture. Making a reputation with her traditional lacquer work in the first decade of the 20th century, she became a critically acclaimed and sought after designer and decorator in the next before reinventing herself as an architect, a field in which she laboured largely in obscurity. Apart from the accolades that greeted her first building –persistently and perversely credited to her mentor–her pioneering work was done quietly, privately and to her own specifications. But she lived long enough (98) to be re-discovered and acclaimed. Today, with her work commanding extraordinary prices and attention, her legacy, like its creator, remains elusive, contested and compelling.

The film is set in Northern Ireland shortly after 1994 cease-fire. Hazel is a Protestant and Malachy a Catholic. Romance between them is threatened by Rohan (leader in militant underground and pal of Malachy's brother Padhar), who wants Malachy to be recruited and fight for the cause and by Hazel's brother Jef, who spies on her meetings.
