Twins are afflicted with a strange power: the power to make others stare. Presented by singer Jackie Clarke, herself a twin, this documentary grabs a fascinating topic with both hands. Among those interviewed are two sets of twins who are romantically involved, a family with twin sets of twins, and an uncanny pair of older women whose thoughts seem to run in tandem, every time they turn up on screen. There is talk of the close relationships twins have, identical medical misaventures, tricks paid on the unsuspecting, and how fathers are often less able to tell twins apart.
