Vessel begins with a young doctor who lived by the sea, and an unlikely idea. Rebecca Gomperts, horrified by the realities created by anti-abortion law around the world, felt compelled to challenge this issue; her method: provide abortions on a ship in offshore waters. Her project, Women on Waves, begins as flawed spectacle, a media frenzy, faced with governmental, religious, and military blockade. But with each roadblock comes a more refined mission, until Rebecca has the revelation that she can use new technologies to bypass law – and train women to safely give themselves abortions using WHO-sanctioned protocols with pills. From there we witness her create an underground network of emboldened, informed activists, working at the radical cutting edge of global reproductive rights, who trust women to handle abortion themselves. Vessel is Rebecca’s story: one of a woman who heard and answered a calling, and transformed a wildly improbable idea into a global movement.
