This British general election campaign has been something of a trudge. If in 2017 the final days were marked by optimism for Jeremy Corbyn’s Labour, this time around, Brexit and a wider political fatigue have rather dulled the mood. Yet there are still issues that could weigh in the Left’s favor — most notably controversies over the National Health Service (NHS), a factor that could still swing key seats away from the Tories and deny Boris Johnson the narrow majority that polls today predict.

This is, then, just the right time for a new film about why the NHS is so endangered. The Great NHS Heist serves just this purpose, going beyond understandings that see the threat to the NHS — and such ills as charges and privatizations — only as a problem for the future. Rather, the film dissects a multi-pronged, piecemeal assault on the UK’s most cherished institution that has already been carried out by stealth for decades. It is thus one of the few accounts that sets out to do justice to one of the most misrepresented topics in the public debate.

Produced over the course of several years while its authors worked full-time, the crowdfunded documentary — which is free to view before UK voters go to cast their ballots — features in-depth interviews with figures like David Graeber, Yanis Varoufakis, Ken Loach, and Danny Dorling, as well as health workers from the earliest days of the NHS.
