A miniature gem, this no-budget, docu-style drama creates an indefinable tension around its mysterious heroine, a newly-qualified live-in nurse whose relations with the family she’s staying with seem to drift beyond the merely professional. The illusion of reality is perfect, thanks to utterly real performances captured by the film’s rough-and-ready camera style. And the mysterious sense of anxiety that permeates the proceedings is impossible to pin down and all the more effective for it.
