Very rarely screened since its original release, this film was originally conceived as Nightcleaners Part 2. A portrait of Grenada-born Myrtle Wardally (b.1936), a leader of the Cleaners’ Action Group Strike in 1972, it features her discussing the partial success of that campaign and also her childhood in the Caribbean. It’s also an experiment – as probing as it is rapturous – in the politics of film form, and a fascinating deconstruction of the idea of Myrtle as a “symbol of struggle, the nightcleaners, working women, immigrants, mothers, blacks”.
